• 418 kWh in one cabinet: Approx. 3.3 h at 125 kW rated power

  • 200 kW PV input: 10 MPPTs, PV oversizing up to 200%
  • < 10 ms switching: Seamless on/off-grid transfer for critical loads

Nov-L418H Key Advantages

NOV-L418H combines a 418 kWh liquid-cooled LFP battery with a built-in 125 kW hybrid inverter. PV strings connect directly on the DC side, and a smart port takes a diesel generator, wind turbine or existing grid-tied inverter. One system covers peak shaving, solar self-consumption and backup power, on-grid or off-grid.

Multi-Layered System Safety

1    Direct PV connection ：Up to 200 kW PV input across 10 MPPTs and 20 strings, so the battery charges straight from solar with no extra PV inverter.

2    Long duration: 418 kWh per cabinet delivers approx. 3.3 hours at full 125 kW output.

3    Multi-energy hub: Grid, PV, diesel generator, wind turbine and existing grid-tied inverters managed in one system.

4   Uninterrupted backup: On/off-grid switching in under 10 ms, and 160% overload for 200 ms off-grid to start motors and water pumps.

5    Room to grow: Up to 10 units in parallel (1.25 MW / 4.18 MWh).

6   Built-in safety: Liquid cooling, fire and smoke detection, aerosol fire suppression and an intelligent dehumidifier in every cabinet.

Parameters

Built for sites that want more solar, longer backup and less dependence on the grid: farms, hotels, fuel-station stores, small factories and remote sites.

FAQ

Can I connect solar panels directly to NOV-L418H?
Yes. The built-in hybrid inverter has 10 MPPTs and accepts up to 200 kW of PV input (up to 250 kW of PV array), so solar charges the battery and powers loads without a separate PV inverter. Existing grid-tied PV inverters can also be connected through the smart port.

How long can NOV-L418H power my site during a grid outage?
At the full 125 kW rated output, one cabinet supplies approx. 3.3 hours. At lower loads it runs longer, and with PV or a diesel generator connected the system keeps recharging. Switching to off-grid takes under 10 ms, so critical loads stay on.
