rferg800 Posted February 18 Share Posted February 18 OK this could get a bit long, please bear with me. I have a 2019 LE II that already has the 12v system in it. 340watt solar, a PWM 25v/30amp Zamp controller, 4 12v AGM batteries in parallel(not sure the size), and a 2000 watt Zantrex inverter. My trailer also has the two 30 amp shore power input plugs. One at the front and one at the rear. Hear is my thoughts/plan: 1st- remove the heavy 340 watts of residential solar. 2nd- build a thin aluminum platform over the trailer to mount 8x200watt flex CIGS panels (ea. 31.5VOC/8.64A) in series. Supported by the 8 awning brackets. 3rd-install in tongue box 48V EG-4 3kW AIO inverter/ charger ( https://signaturesolar.com/eg4-3kw-...r2ooEFRdHYEsl9hcu-afUiL7PX8vjfHdggB4q3.VnU9vH ) 4th Two 48V 100AH EG4 WP batteries. This should give me a silent true 3000 watt solar gen. Here is where I need some input. First I would like to keep the rest of the 12v system in place. So to feed the Zamp controller would I be able to feed 20-30 amps of 12-24v through a step down converter from the 48v batteries in place of the 340 watts of original solar panels I removed? Second I would like to use the front 30amp shore power plug as the AC input to the EG4 3kW AIO inverter/ charger and treat the AC output of the inverter as the shore power to the trailer. I understand that the 3kW from the inverter wont equal the 3600watts from a 30A shore power supply (3600watts). The EG4 3kW unit can handle 5kW surges, for starting the air conditioner. Thanks all input welcome Robert 2019 LE II Hull# 466 TV 2021 Chev Silverodo 1500 HC Link to comment Share on other sites More sharing options...
