Not really ready for Lithium Iron phosphate batteries

Latest Update - Bluetooth died after one day. Tried everything to revive it but nothing worked. It should also be noted that there are quite a few solar charge controllers out there that claim lithium battery compatibility but, in my opinion, it is not true. These solar chargers just seem to be minor upgrades to chargers that were suitable for sealed, AGM or gel batteries. Lithium batteries have a very narrow operating voltage. A tenth of a volt means the world. So these charge controllers that try and regulate charging based on voltage only can't really do the job. You have cable losses always and whether you contoller reads high or low will depend on amperage and loads. For lithium battery charge controllers you need to be able to read the voltage at the battery terminals and you the truth is you need to be able to read the current going into or out of the battery so you can coulomb count. Knowing the true state of charge of the battery is probably impossible without this. A lot of voltage only charge controllers will regulate amps to the battery whether the battery is dumping 20 or more amps to a load or receiving an excess of amps (i.e. charging) because the voltage is close to the same on the battery. If my charge controller can put out 20 amps (assuming the panels can supply this) and I have a 25 amp load then my charge controller SHOULD go all out and supply all the amps it can. However, if you battery is near full the charge controller will see this full voltage and down regulate amperage. On the other hand, if the charge controller can sense amperage in and out it can do what it should in this case. So, long story short, the Bluetooth failure and the voltage only sensing of the Renogy solar controller made me return it today. Going to give Victron a try which coupled with their smartshunt seems able to do what needs to be done. We will see. ************** Update..I did find that when using the Renogy Lithium preset in the app it is possible to still edit some values and keep the equalization turned off. At least it appears that way. The manual does not explain this and the first few values I tried to change would not let me select them. Finally, on a later visit I scrolled down further and found some items in a lighter shade of grey that could be changed. When you changed them, other items were automatically adjusted and you have no ability to alter those. Fortunately, this is a situation I can probably live with. Another issue is that the Renogy senses a different voltage than I get when measuring voltage at the battery terminals. This is not a surprise as you always have line losses but I suspect this value will not be constant and vary depending on amperage load and whether charging or discharging. Problem is if you want to offset the presets in the renogy BT app to account for this you can't really do it as you need different presets for different situations. What Renogy and everyone else should do (and the good solar charge controllers allow you to do) is have a different dedicated line for measuring voltage at the battery terminals. Renogy would do themselves a big favor if they improved their manuals and discussed some of the settings in more details. Also, why not stick to the same terminology used by battery manufactures (like bulk, adsorbtion etc. ) instead of using boost (which they never really explain but seems to be the same as bulk). Since I was able to change the parameters I most care about I have changed my rating of the Renogy to 3 stars from one. You can make it work but your BMS is still going to be doing some of the heavy lifting. **************** My overall opinion of Renogy products has really dropped during the last few days. This product claims Lithium battery compatibility but when you look at the values that are preset for lithium many of them are way to high and close to being unsafe. Certainly they do not allow a LFP battery to be kept in the 20 - 90% range recommended for long life. Yes, they have a user setting where you can alter the values but you cannot turn off float or equalization modes in the user settings. Beyond this, Renogy provides so little documentation on lithium charging recommendations and issues and it is hard to find anything on the web to address my issues. And in a number of instances not only is their software and programability inadequate, they do not even take the trouble to allow you to input values or read values for 24 volt systems. Instead they want you to multiply or divide by two! It is not that it is hard, it is just so unprofessional and kludgy and has to make one wonder about the whole product and the company that stands behind it. This really seems to be a product that was never meant for lithium from a company that is living in the dark ages. Needless to say, I returned the product.

Well priced Controller - a definite must for small-scale/camping solar applications

Great replacement for the PWM controller that came with our Renogy Solar kit. Initially we had the Renogy PWM 30 AMP controller and it was an entry level controller in all respects. The previous controller was limited to a 12 volt battery source had 2 lead pairs, one for solar panel connection and the other for the battery side connection. Any load connected to the battery array had to be connected directly to the batteries and was not governed by the controller. Also you had to rely on LED indicator lights To determine when the controller was in charge mode versus float mode. Adequate for an entry level controller but not great. Now lets talk about this controller. First, this controller is capable of 12 or 24 volt wiring installations. 24 volt DC is superior to 12 volt DC because it cuts the Amperage draw in half on the DC end. A 1.2 Amp TV running on AC/120 volts will require 12 Amps on the 12v-DC end to meet the same 140 Watt requirement. A 24 volt DC setup will reduce the amperage requirement down to 6 amps on DC, which means your DC wiring gauge doesn’t have to be as robust when supporting a 24 volt application. Secondly, the LCD display is great and is a must for a solar charge controller. It’s not enough to know that the solar cells are charging the battery, you may also want to know how “fast” they are charging the battery and whether or not the panels should be angled to reach optimized charge rate. The LCD screen also provides a percentage estimate of battery remaining in addition to the amps that are being supplied by the panels, along with a running amp-hour accumulation of charge provided the panels over a period of time and current battery voltage. Third, it has a pair of positive/negative load leads that permit connecting appliance loads up to 20 Amps DC. It’s not necessary to use the load leads for connecting the devices that run off the battery, but the added advantage of using them is that your battery array is protected from over-consumption, as the leads shut off usage on the battery once it reaches a certain level of discharge in order to protect the battery array. I’ve only used the new controller once, but the instructions were easy to follow and I made a laminated copy of the LED and Menu options as a quick reference guide that will go along with the kit on camping trips. Currently the array powers my 400 Watt (4x100W) kit and 2 VMAX 125ah batteries wired in parallel, but I am seriously thinking of doubling the panel array and adding 2 more batteries in a series/parallel configuration to take advantage of the 24 volt capabilities of this controller. Quick Note on the 100 Watt Renogy panels: When I measured the charge current of the 4 x 100 watt panels connected in Parallel I noted an 18.5 amp charge rate on the new controller or ~4.6 amps per panel. That seemed low to me given that 400 watts/12v is around 33.3 amps, or 8.33 amps per panel. In discussions with Renogy support I found out that the 100 Watts is calculated at 17.9 volts * 5.7 amps, where they use the maximum charge voltage by each of the panels as basis for the calculation. Just something to be aware of when you are reading sub-5 amps per panel charge rate on your controller. This new controller works as advertised, was relatively inexpensive for what it does, and I may update the review again in 12 months after running it a few more times for a consistency check.

Works well

E1 error is frustrating, but after kinks worked out, product working properly.

Works well, good installation manual. Needs a better programming manual.

I'm using these for a few telemetry stations we have on solar power. They have worked well on lead-acid batteries. They install easily, and have worked flawlessly to date. I'm not at all impressed with the programming sequence, however, and the manual is pretty useless here. Thank goodness for youtube, which does help explain it better. Recommended, along with youtube's programming instructions.

Splits apart when you tighten wires to hold them in place

The manual comes with a warning, not to over tighten the wires, however, when I came to fix them they would not tighten up enough to hold the wires in place I realised that the box had split apart! It is now held together with multiple wrappings of fibreglass reinforced tape to hold the case and the wires together. Now past 30 days otherwise I would have sent it back and bought a decent one fit for purpose instead of something that falls apart when you tighten up wires which anyone should know puts a lot of stress on any component. Therefore, there must be some kind of design flaw. I have made two attempts to register this product but it will not accept the SKU which I obtained from the Renology website. I have contacted support about this but can only do it by reporting a fault. Being unable to complete warranty registration does not inspire me with any confidence concerning this product or after sales support and warranty claims. I received a prompt reply and have been assured by Renology that they will fix their website. Also, the warranty is available upon proof of purchase and it is not necessary to register the product. I will update this review as things progress The battery percentage charge reading is erratic, It's still charging when reading 100%, it should be used as a guide and cannot be relied upon as an accurate reading.

Not as clever, as you'd think......

Easy to install, but a few moans - * No back-lit screen, so you cant see whats going on at night.....in this day and age, theres no excuse for not having back lighting.... * the terminals clamp the wires IN FRONT of the terminal clamp, not behind (depending on your perspective).....anyone whose ever fitted a plug to anything, or wires into a plug socket on the wall will get this.... * The 4 status lights on the front of the panel, all look like they are illuminated, when the useual 2 are on.....at a glance, you think you've got an error code up, but its not....clearly, the 4 LED's are not shielded from each other inside the caseing, and get a bit of reflection off the ones that are lit...... * the button procedures (left and right, up and down) are quite complicated, and its easy to miss a step....YouTube is full of tutorials for the product, for this very reason...... To be honest a couple of guages to monitor battery strength, and "volts in", would do the job, at a fraction of the cost.....the advantage of this system, is that you can set it up to shut down the charging, and tell you what its doing by bluetooth or the internet, (extra module at extra cost) but i am sure, there are other ways around that, that are cheaper..... The "at a glance" screen gives you the basics, * is charging taking place, * is the system using power, * how much is left in the battery (symbol) but as above.....a couple of cheap gauges, would have told you that anyway...... I meant to give it 3 stars, but pressed 4 by mistake......

Not fit for purpose

Stay well away from this rubbish, installtion started bad when I realised that the mounting plate was specifically designed to make it almost impossible to be mounted while the unit is in place as the unit prevents you from getting to the mounting holes when all they needed to do was make the back plate 10mm bigger, but this didnt prepare me for the completely useless terminals that use the softest metal on earth as your terminel screw that instantly round off the second you make contact with a screwdriver, and for some reason the terminal screws require masssive quantities of torque to turn despite never actually gripping any size wire you try to fit in them, I was hoping to fit in 6awg but tried both 6 and 8awg will not grip the wires just fall straight beck out again, you have 2 options, either strip the unit apart invalidating any warranty to replace the terminal points with something that can actually hold wires or remove the M5 terminel tightening screw and replace with a long steal M5 Screw and effectively use that to bolt on a M5 terminal ring and hope that M5 is thick enough for the current you plan on drawering through your system, complete and utter rip off and poor engineering this is not a charge controller its a kit of bits that you might be able to salvage and turn into a charge controller wish I bought epever now, really should have lisetened to the warnings from other reviewers about the poor quality terminels, I decided to open it up and replace the terminals or at least try to fix the badly made ones fitted, to my horror I could see the paper thin metal that connected the treminals top and bottom and see how easily it twisted when trying to turn the screw, this cannot be safe if running at 40 amps its simply not enough metal for that level of current to travel through but explained why these terminals are so flimsy and unusable please dont make my mistake and waste your money on this junk, if they cant even fit it with a set of terminals that work I can not imagine how bad the rest of the unit must be of such shoddy cheap workmanship and parts and they expect me to trust them with 40 amps running through this piece of rubbish without burning my shed down, not a chance buy a cheap 10 pound PWM at least they come with proper terminals that actually secure wires. The supplied manual is also incorrect, for instance page 20 refers to changing parameters such as charging charge voltages but infact if you follow the instructions the only parameters it allows you to change is battery type and if you select Li then you can select between 12v or 24 volt since the controller cant detect that itself and needs a helping hand when using Li batterries but you cannot change the charge voltages as the manual elludes or instructs, presumable your need to spend more money on the BT-1 app controller that another reviewer said doesnt work either to change battery charge state and voltages, this really is a dissapointing product and has put me right off buying anything with the name Renogy attached to it I write procedures for a living to build and use complex pieces of medical equipment it really isn't difficult to write and verify such instructions are correct and work so any company that produces manuals that simply don't work I always feel says a lot about their quality standards of which Renogy has firmly placed themselves on my list near the bottom rung buy epever or victron and save yourself a headache and have a proper charge controller you can wire something to safely and know you can control when needed without spending more money on devices to use apps that may or may not work, I had been enjoying my small off grid solar project right up until I made the mistake of paying Renogy for this headache

Has a mind of its own.

Installation is simple enough although the unit is a lot bigger than some on the market. Appears to do its job well but it is a bit like guesswork as one moment it says the batteries are dangerously low, the next it says they're 100% Van electrics all working well but if you are a control freak, forget it - it will drive you mad and for this money, to be blunt I expected better. Buyer beware! When I tried to return this unit I was told it would be replaced NOT refunded as soon as I took down my review. Thank goodness Amazon sorted it for me!

Junk! Software with bluetooth dosen't work - Renogy has AWFUL 'support'

App/Bluetooth that I wanted to monitor from an phone doesn't work. Faulty erratic readings and in short I returned it along with the BT module. Tried many times to contact Renogy and they have NO UK phone number (always a red flag for a large company). Have to go on a forum to ask others to help you. MANY with the same complaints and Renogy have made NO statement to fix it, they actually bought a new app out which has NO battery capacity readings. In short it's a headache. Wasted 2 days playing around and a week of trying to contact them. Great panels (they were) awful support and software. Consider other options if you want to monitor without manually checking MPPT controller.
