Conversol MKS-III 5000W 48V Off Grid Solar Inverter MPPT 80A 450Vdc Charger Sine Wave with Parallel Function

Noticed: This is a used product in full working conditions. Please expect cosmetic damages, like scratches.

Wide operating solar PV Voltage from 120-430Vdc. It is easier and more efficient to install photovoltaic arrays with higher DC voltage. The Conversol MKS-III operates even without a battery connected. The AC load can be fed directly from the solar panels and the external AC generator. If a battery is required it can still be installed to the 48V terminal.

DC 48V connection terminal is suitable for GEL, AGM, Lithium, LiFeP04 Batteries. The inverter lithium port is connected to a serial protocol (RS485) and communicates with the BMS of all Pylontech batteries (US2000C/US3000C/US5000).

The bms cable is required with the correct pin layout. It can be purchased here
