30A MPPT Solar Charge Controller 2018 100V PV Input Support Lithium Battery Charging Backlight LCD Negative Ground 12V 24V Auto 780W Solar Panel Charge Regulator Tracer 3210AN

ZHC solar sold me this charge controller in 2017 and has given exception customer service. I would have NO hesitation buying from them again. This is an excellent charge controller I've installed in my RV, powering 800 watts of panels. I have 3 separate #6 copper pairs of THHN wire running each to the solar panels, the batteries, and the load (RV). The controller monitors and manages each of the components separately.I purchased the wifi transmitter device from EP Ever that plugs into the ethernet connection on the controller that I use to connect to the MPPT controller wirelessly through their app on my android phone. Through this I can pull real time charging data, view solar power inputs, and battery status and voltage and see the load draw and drain on the battery. ALL on my phone, it is awesome.I can change charge and load settings through my phone. I can program to turn on/off the trailer load at certain times so that it exercised the batteries when stored and the RV is not in use. Overall I would highly recommend the MPPT controller and ZHC solar.

We ordered it in February, worked like a champ until sometime in July when it started locking up and not charging the batteries.The batteries would last one week or two depending on whether there were 2 or 4 batteries on site. The charge controller would stop outputting power. It would have to be disconnected from the panels and the batteries entirely to reset the controller then it would work for a few days to a week.ZHC refunded me, no fuss, and I ordered a replacement, same unit. I'm sincerely hoping the failure was a fluke.Early in the mornings, before the sun even hits the panels directly, it is pulling 17v from the panels, converting that to 24+v and charging the batteries as the sun rises.

The unit had a short in the board. I would buy from a different manufacturer. If you pull on the wiring, the unit would start to work and I checked the wiring and no problems.

I installed it, after two months it didn't charge the batteries. I don't like it.

So after using this product for more than a few months now, I have to say that I do love it. Ive been through half a dozen charge controllers and this one, especially for the price , was more than worth it!

Replaced our cheapie starter PWM with this and love it! If it had a dedicated USB port or two it would be 5 stars. Functionality and power retention seem excellent so far. Very happy with this purchase.

Controller did not have a auto pick for AGM battery but it can be set up for AGM battery. It is installed and working effectively. Delivery was fast and it arrived in good order

Kept having problems with my system holding a charge ... took this unit back out and now works fine. I think this is a very low quality controller.
