Hybrid Inverter | Single Phase |
Low Voltage 3/4/5/6kW
The Iconiq Energy single phase hybrid inverter (3–6kW LV) brings residential and small commercial sites a compact, capable way to manage power from battery, grid, and renewables in one unit. Because single-phase loads are the most common configuration in Indian homes and small businesses, this inverter is designed around the realities of variable grid supply and growing battery adoption.
It is available in 4 capacities — 3kW, 4kW, 5kW and 6kW. Moreover, with an IP65 rating, sub-10ms switchover, and support for up to six units in parallel, this single phase hybrid inverter adapts to a wide range of site needs without requiring complex retrofits. As a result, installers and site owners get a reliable, future-ready platform from day one.

Why a Single Phase Hybrid Inverter Suits Indian Homes and Small Businesses
Indian residential and small-commercial sites typically face wide grid voltage swings and occasional outages, so the inverter at the centre of the system needs to handle both reliably. Therefore, the 3–6kW LV model supports a 184–276V AC input range and 45–65Hz frequency tolerance, which means it stays stable even when the grid does not.
In addition, 150–200% PV input oversizing across three MPPTs and a 200–400% grid input range give installers the flexibility to right-size the array without changing the inverter. Furthermore, the smart fan only runs above 50% rated output, keeping the unit quiet in day-to-day operation.
