SUNINVM 3kw 24vdc off grid solar inverter with 40A MPPT charger

SUNINVM MPPT series

Solar/Grid Hybrid Inverter with Charger AND MPPT Solar charge controller

1.System Introduction
Solar/Grid Hybrid Inverter with Charger AND MPPT Solar charge controller system is a set of battery charging and discharging control , PV mains switch control and inverter control in one multi-functional integrated system, mainly including PV array, grid, battery, hybrid off-grid inverter and the AC load, PV array absorption of solar radiation and translate into electrical energy to provide power for the entire system, utility power switchover and Inverting control function, also could converting DC power from battery to supply power for AC loads. System Priority mode is PV mode. PV controller and Grid charger achieves the intelligent battery-charging control. The inverter inverts the DC to AC for the load power supplying ;and automatic control the  start-stop of Grid charger if needed. the best to use the solar energy and the continuous demand of electricity. It's the preferred solution to solve the public grid or less developed areas residents daily electricity

2. Internal structure

Hybrid Inverter including PV Charger,Grid Charger, Inverter and Controller, using a common DC Bus mode, as the output of Battery, PV Charger, Grid Charger and Inverter merge into DC Bus. Meanwhile, DC Bus is battery's charging current path, and PV charging is priority than Grid charging.
