- GV-10-Li-14.2V, 10.5 A MPPT Charge Controller for Lithium (4S LiFePO4) Battery

Works well as long as you don't put too much OCV through it. Oops, my bad. But Ryan worked with me and sent out a new board. Excellent customer service. Now I just need to remember not to put 35 OCV to it.It is small enough to fit into an Apache 1800 case that I'm making into a 12 volt power distribution box for portable use. Tried the amatuer radio on 80 through 10 meters while charging a LiFePo4 battery and it is "Radio Quiet" as advertised. If I need another I'll buy this again.

If you are a portable Ham radio operator with solar 150w or less this is the only Solar Charge Controller that will give you almost totally clean of RFI issues from your solar controller. It does have a few RFI artifacts on 80-40m but most were S2 and sporadic but all low enough S units to work on top of the RFI. Higher bands I found nothing but clean air. This is the only portable controller I have found to achieve this. It’s made in the US and their customer support is amazing. Want real quality and talk to real people who designed and make them? Go no further than Genasun.

RF quiet. If you are looking for use with ham radio, this solar charger is HF RF quiet.

Great little Solar Chargers but wee need ones that can handle higher Amps and voltage!

It worked as expected. Really like the size of the controller.

I paired this with a 100w folding solar panel, adding some adapter cables for the panel and battery connectors. I can now keep my 20Ah LiFePo4 battery topped off all day using with my HF ham radio setup.

Easy to put into operation it just works.

Using this on an occasional-use low-draw piece of equipment. Charges fine using solar or with a DC power source.
