80A Solar Charge Controller PWM PV Solar Panel Charger Regulators with LCD Monitor 12V 24V Auto 960W 1360W Large amp Power Input Energy Controller ZHCSolar

I don't know much about the technical aspects of electricity installations but my husband bought this and so far it works perfectly! We live in Haiti and electricity availability on a daily basis is a big challenge so it was very important to us to have it available especially we have a lot going on (fridge, wi-fi, a/c...) + a 3 year old toddler with an ipad lol. Anyway, it works well with 4 solar panels installed (don't really remember the capacity of each). But in regards to my husband's satisfactions. I recommend this product :-)

Works well - been using for a year now - I have it connected with 3 100 watt panels to 4 12 volt batteries.After my batteries run down - and full sun - it puts out around 11 amps per the display - and charges the batteries fairly quickly. I can toggle thru the display - but it won't stay where I leave it instead it defaults back to battery voltage. I would rather it stay on the charging amps all of the time.Good unit - somewhat middle of the road or a good starter unit. Now that I have learned more I would have spent more for more information on the charging process and the load process.

so far it's good. can put heavy wires into the connectors and it seems heavy duty. It displays volts and amps and has a load connector. It doesn't seem to have charging stages but the max charge voltage can be set. It was charging 32 amps and did not even get warm at all. It does have a probe on top that increases voltage when temp is low, 12 degrees C produced 14.2 volts max at full charge. It displays temperature in Centigrade. Other controllers I have had produced too much volts and overvoltaged the invertor in cold weather but this didn't. I will probably attach more panels to this as it is rated at 60 amps. I have had controllers go bad after the warrenty was over, so I hope this one is better than that. Oh by the way this keeps a running account as to how many volt amps were produced and also how many went to the load terminals..

Read entire review before deciding if this is for you, I personally don't recommend it. I've updated it 2 times since the initial review because of new problems showing up.Summary: If you do use this do not bet you battery bank on the low voltage disconnect, 2nd its not a true 80 amps, the clicking noise I had was because I had 1425 watts of solar panels @ 24 volts coming in (61 amps), its only rated to 1380 watts or 59 amps for an 80 amp model. The description has since been updated to reflect the lower wattage numbers, I guess basic electricity theories in China are different? (24.0v x 80a = 1920 watts) I've never had more than 25 amps of output, even on full sun days when the 30 running next to it with 570 watts going in was putting out 19 amps. I'm giving it 2 stars because it does technically function as a charge controller and does tell me what the temp is on the wall where its bolted. Everything else you expect from the description it will not do.Its been online for 10 days controlling about 40 amps of power. It had basic setup already done and I tweaked it a little, it runs in tandem with another manufacturers PWM 30 amp controller. They don't see each other and don't care about each other. I was able to fit 4 AWG wire into the terminals with no problem. The setup paper is very vague and I wish I could get more info about the specifics. Biggest question is, how much can the light output handle in amps? Currently I have it running to the control side of a relay for fears it can't handle 50 amps continuous. Things that would make it better would be an external battery temp sensor and a back light. Overall it gets 4 stars, well worth the money but, it could use improvement. If you have more then enough amps coming in and panels match the battery bank voltage I say jump on this PWM controller. If either of the previous are not 100% true go for an MPPT. I will update this review as I get more hours on the unit.Well 2 months in it now controls 60 amps and I've had to lower its rating. Still running in tandem with a 30 amp controller and the 30 amp out charges it. This one has begun making a very rapid clicking noise and doesn't charge steady anymore. I'm worried that it may not be 4 stages and it now has too much input. I'm going to lessen the input amps and try different brands and may end up jumping to the MPPT.It is officially removed from service after just 5 months, as the days get shorter I'm very reliant on the load circuit to function properly. Most controllers let you pick the low disconnect voltage, this one will not let you set the LVD above 25.1. This is a problem when you've connected a stock tank heater to it that draws 50 amps. Last night I manually turned the heater off because it was going to be 50 degrees today, when I arrive home my voltage is at 25.1v and it was still powering the heater. I assume it automatically turned the load on when it hit my set reset point of 26.2. and sucked up all the amperage until the sunset. I also need to assume now that when set at 25.1 it doesn't turn off till 25.0 . Full charge on a 24v bank is 25.4 so, now just 90 mins after sunset I'm at 80% state of charge and it needs to run the electric fence and pasture lights all night. Usually I'm 24.9 volts at dawn with the short days, I figure I'll be at 60% or less in my batteries at sunrise, this is bad and it would drastically reduce the life of the batteries if it occurred nightly.

This controller worked well for about 4 months, then it wouldn't stop charging the batteries when they were full. Not only did I have to replace the controller but had to replace my batteries because they were ruined. I would recommend buying a better controller.

Good instructions and easy to program and it works as designed. You can see how many amps and volts you are putting into your batteries..

easy to connect, easy to understand, and handles our 4 panels which our old controller did not.

Overall worked correctly. The thermostat sensor was cheep. I had it charging two 12v batteries from four 100w panels with no issues. I upgraded to a mppt controller after 1 month of use.
