SR Series – Hybrid off grid and on grid inverter with CT Sensor

Hybrid on and off grid solar inverter

SR Series solar inverter is an intelligent hybrid on and off grid solar inverter, combining functions of inverter, solar charger and battery charger to offer uninterruptible power support in portable size. With CT sensor and new design hardware, SR solar inverter can guarantee no exceeded PV power feedback to the grid against requirements, and operating without battery function can further save cost in setting up home use solar system.

Features:

Touchscreen display
PV and utility power take the load at the same time(can setting)
Output power factor PF=1.0
On & Off Grid with energy storage.
Energy generated record, load record, history information and fault record.
Language and time setting.
Structure with dust filter.
AC charging and AC output time setting.
Charging voltage and charging current timing.
External WI-FI device optional.
Parallel operation with up to 6 units only available for 3KW/4KW/5KW.
Connected with battery optional.
Wide PV Input Range.
Built in CT sensor monitoring the power consumption and make sure no excess PV power feedback to the main city.
