Y&H 4.2KW 24VDC Solar Hybrid Inverter Built-in Air Switch and Lightning Protection,Pure Sine Wave AC220V Dual Output,WIFI+BMS dual communication,MPPT 120A Solar Charger

4200W Off Grid Solar Inverter 24V Built-in 120A MPPT Charge Controller, Pure Sine Wave Inverter Single-phase output 230VAC, 4.2kw new all-in-one inverter combining functions of inverter, solar charger and battery charger to offer uninterruptible power support in a single package.

120A MPPT Solar Charging Inverter, MAX. PV Array Power: 6200W, Max.PV Open Circuit Voltage: 450Vdc; Starting voltage>90V, MAX.Charging Current:120A, PV Array MPPT Voltage Range: 60~450Vdc;Cold start function(23V).

AC input has built-in air switch and surge protector, which is convenient for wiring and prevents over-voltage impact on the power grid; battery input is equipped with an air switch, and PV input has a built-in lightning protection device, which can effectively resist lightning strikes. The comprehensive protection configuration makes wiring easier and safer for users, reduces the risk of fire, and ensures stable operation of the system.

Setting range is from 20.0V to 23.0V for 4.2KW model.Increment of each click is 0.1V. When the battery voltage falls below the setting range, the Main OUT port stops working. Only the Second Out port will work. For areas with frequent power outages and loads that can't be blacked out, you can set the battery voltage to 23 V. Keep more battery capacity for emergencies. If the battery voltage is higher than 23V, the Main OUT port will continue to work.

On/ Off-grid working mode, you can use inverter as energy storage device without power Grid (Off Grid). Maybe you will also like to reduce the household electricity bill through it (On Grid).;Can be accessed to a variety of household and office loads, including refrigerators, lamps, televisions, fans, air conditioning and other loads.3 charging modes support: Solar first,Solar&Utility and Only Solar.
