OG Series — single-phase off-grid inverter, 5/6 kW
Country: China · Model: OG Series
The off-grid single-phase OG Series inverter, rated 5 or 6 kW, works from a 48 V battery and solar panels without a grid connection. It is installed at country houses, farms and sites with an unstable line, where backup is built from a battery, PV and a generator.

Description
The inverter accepts both lithium and lead-acid batteries with an operating voltage of 40–60 V, and the charge/discharge current is 120 / 140 A. Solar panels are connected to a single 28 A MPPT with a range of 90–450 V, so the string is built in series from panels facing the same direction. The inverter can also work without a battery, directly from PV, although then the output depends on the sun. Switchover to backup takes less than 4 ms, and the short-term 200% overload on the AC output handles starting a pump or compressor. The inverter controls the generator itself, and the system status is visible through Wi-Fi monitoring. At 9.6 kg the unit is hung on the wall without a helper.
How to choose
Between 5 and 6 kW the choice is made by the sum of simultaneously running loads, taking starting currents into account. An off-grid inverter is not intended to feed energy into the grid, so if selling surplus or three-phase backup is needed, the hybrid X3-HYBRID G4 rated 5–15 kW is taken. Lead-acid batteries are suitable if they are already on site, but lithium LFP gives more cycles and deeper discharge, which reduces the required bank capacity.

FAQ
Can the OG Series work without a battery?
Yes, the inverter works with a battery and without one. Without storage the load is powered directly from the solar panels during daylight.
Which batteries suit the OG Series?
Lithium and lead-acid 48 V batteries with a voltage range of 40–60 V are suitable.
What are the charge and discharge currents of the OG Series?
The charge/discharge current is 120 / 140 A. The bank capacity is chosen so that this current does not exceed what the battery allows.
What is the PV input voltage of the OG Series inverter?
The single MPPT accepts 90–450 V at a current of up to 28 A.
Does the OG Series control a generator?
Yes, the inverter has a generator control function and Wi-Fi monitoring, so the backup source is switched on by command from the inverter.
