    Have it mounted to keep my DC marine battery charged for my boat lift motor. Cranks up the boat every time, so it must be keeping the battery charged. Great value and easy to set-up

    Yes I like it. I am new to and experimenting with solar. I bought this Newpowa 20W solar kit to power a 2.5A wifi security camera 600' from my house. (no 120VAC). I used a Zoom 12v10A LifePo battery, and LaView 2K PT camera. I wrote to Newpowa and requested their programing remote which is clearly required by their own instructions for LI batteries. They immediately replied and sent the remote within 2 days. The solar panel, the remote, and the MPPT is solid quality, IP65 I or better. Yes I could buy an RF link set, but this is how I learn and Newpowa customer service after the sale, and initial quality for the price is plenty good for my needs. Yes I recommend them.
