Eternal Inverter 
New 60-450VDC PV Input 120A MPPT On/Off Grid 4.2KW 24V Solar Hybrid Inverter
S-4.2K Series is an On/Off grid hybrid solar inverter.Built in 120A MPPT solar charge controller. It can not only operate normally in harsh environment, but also automatically complement each other between on-grid and off-grid modes quickly to ensure that the load will never be cut off.
Features
Pure sine wave AC clean and stable output.
High photovoltaic input voltage range 60-550VDC
Compatible with 50/60HZ
WIFI&GPRS module realizes remote monitoring, used for IOS and Android.
A key to restore the factory settings
It can run without battery
Built-in lithium battery automatic activation
Wall-mounted, built-in dust-proof kit to deal with harsh environment
Over-current protection/Over-voltage protection/Under-voltage protection/Over-temperature protection
Automatic identification of battery voltage
