Hello , new here and wanted to post about my off grid solar system. I’m using Renogy components. Main part Renogy 4800w 48v inverter/charger/controller with 4 - 12v 200ah gel batteries fused 200amps and a battery monitor. Core One BT/wifi monitor to remotely watch system . This system provides solar power to 120v loads , bedrooms , fridge and basement freezer , house lighting loads , HVAC , and outdoor landscape lights through a 48v to 12v converter rated 20amps . ( led landscape lights ) . Solar array is made up of 4 strings of 5 - 100w panels each totaling 2000watts at 20amps/120vdc. Max Pv of controller is 145vdc . This is a High Frequency inverter , I do not have high motor loads is why I chose to go with this vs a low frequency inverter with big transformers which has a flywheel effect for heavy motor loads . Only time will tell how long the switching transistors will last , hopefully years ….. During spring/summer/fall great power output . Hardly no utility at all , in 8 months utilities charged batteries twice. Cloudy rainy days I still get 50% solar output . But I live in northern climate so heavy snow , panels are on roof so first 1/4” of snow , no output , so I just run inverter in UPS mode . In future will be relocating to ground array to keep snow off. But I still have power back up for lighting/heating. Up to 48hours with no utilities or generators. I’m happy with that . We lose power a bit in wintertime. I would rate Renogy inverter 9/10 . Very quiet, seems efficient, lightweight, powerful. User programs are ok , but could be better . Wiring termination needs to be better , just small termination blocks . Batteries are very well built , in future will be switching to lithium. Just cost stopping me now .
