Hybrid Solar Inverters · 3 kW → 240 kW

One box replaces
three separate systems.

Most sites need a solar inverter, a UPS, and a DG ATS box. Infozeb hybrid does all three: solar to DC, battery management, grid sync, and load switchover under 20 milliseconds.

Why hybrid · one cabinet, four jobs

Three boxes, one box.

A typical Indian site runs solar, battery, grid, and DG — each from a different vendor with its own SLA. Infozeb does all four in one cabinet, one warranty, one phone number to call.

Same controller.
Eight cabinet sizes.

Same firmware, same app, same training from 3 kW (wall-mount for a flat) to 240 kW (floor cabinet for a factory). Only the cabinet and breaker size change.

Faster than your
lights can notice.

Indian grids collapse without notice — voltage dips, brownouts, split-second outages. A standby UPS has to detect it, switch over, and start. Infozeb hybrid runs in online double-conversion mode: the load always sits on the inverter, never the raw grid. Grid fails, nothing transfers. Battery takes over in under 20 ms.

A standby UPS or DG ATS panel needs to detect the outage, open the grid contactor, start the inverter, and close onto the battery. That's 200–800 ms of dark — long enough to drop computers, trip motors, and reset PLCs.

The Infozeb hybrid never needs to start. The load is already on the inverter; the grid is just a charging source. When the grid goes away, the battery takes over in under 20 milliseconds — well below the threshold that any connected equipment can sense.

That's why we call it a hybrid inverter, not a backup inverter: there's no failover. The load only ever sees clean sine wave from one source — the inverter itself.

Which SKU for which job

Sized for Indian sites.

Four common setups. We size off your actual load profile, not nameplate specs. Call us for 20 minutes and we'll send the right SKU.

IZ-HI-5

Home backup

Single-phase 5 kW + 10 kWh battery. Runs a 2–3 BHK villa overnight, including fans and one inverter AC.

IZ-HI-30

Society + clinic

Three-phase 30 kW + 60 kWh. Common-area lighting, lifts, pump, plus essential clinical loads.

IZ-HI-60

Factory peak-shave

60 kW · 2× MPPT. Trims demand charges through the day, runs critical line through any grid event.

IZ-HI-240+

Hospital + EV hub

240 kW units paralleled into 480 kW or 1.92 MW utility blocks. Master/slave sync, hot-swap on fault.
