I put 3 280w pv panels in series charging one 100amp 24v lifepo4 battery feeding 20amp (0.2C charging rate) in perfect conditions on mppt mode and the verdict is : awesome charger controller. maybe a little hot but i put one auxiliary pedestal fan front of the charger and the heat go away. very awesome the easy way charge control of the lifepo4 battery. i will recommend 14,3 volts in mppt charging mode with the lifepo4 battery. feature. means 28.6 volts charging the 24v battery (auto select the voltage when connect the battery power) i love this thing.. .pwm chargers now are obsolete.

I like these because I use lithium batteries and these can be adjusted accordingly. I don't like to charge them over 80% charge and I am able to do that with these devices, I found other devices but were brutally overpriced. For the money and for what I needed. These seem to be the best fit. I have been using this type for over a year now with no problems. Lithium batteries will last longer if you don't charge them over 80%

built well for the price paid. Just enough built in utility and settings that can be used to customize your solar and battery setup. This controller is great for a moderate to small solar subsystem.

An extremely fast acting solar charge controller! Reacts very well to changing light environment. The high voltage input is definitely a big plus! Will get another one soon for powering my basement Ham Radio shack. Thanks MyPwr, KA9DSL 73's
