PRODUCT: SUNER POWER 12V Solar Battery Charger Maintainer, Waterproof 20W Solar Trickle Charger, High Efficiency Solar Panel Kit, Built-in Intelligent MPPT Controller.
REPORT: I live in a condominium, and there is no power access at my storage facility, so when I winterized my model 1575 with two AMG 100 amp hour batteries, I had to figure out a way to keep them healthy with trickle charge. My solution, this 20 W solar trickle charger. I mounting it to my front hitch, and I plugged it into my Go Power Solar on the Side plug. I needed an adapter because of reverse polarity. I have checked the batteries several times and the readings are always 13.4. volts, I'm so pleased this worked out.
What was particularly helpful with this solar trickle charger is the fact that the built-in adjustable frame and bracket mounts allowed me to mount panel on pressure-treated wood, then adjust the angle of the solar panel so as to maximize winter sun exposure.
I hope this information proves to be helpful to others.
