Inverters

Growatt WIT 29.9–50 kW Hybrid Inverter

Three-phase C&I hybrid inverter family (29.9/30/36/40/50 kW) with 4 MPPT, 200–900V battery window and IP66 enclosure—built for commercial PV + storage projects that need UPS/black-start behavior, weak-grid tolerance, and clear RFQ inputs.

Key features

Feature 01

PV handling for complex roofs: 4 MPPT with up to 2 strings per MPPT and 40 A input current per MPPT.

Feature 02

Battery-side flexibility: 3 battery channels (55 A × 3) across a 200–900 V window for C&I ESS designs.

Feature 03

UPS and black-start capability with ≤10 ms transfer, plus 100% three-phase unbalanced output for demanding sites.

Buyer FAQ

What is the difference between 29.9–50kW XHU and 50–100kW HU?

XHU covers 29.9–50 kW with a 200–900V battery range and 4 MPPT. HU expands to 50–100 kW with different MPPT counts and a higher battery voltage window. Share your target kW and battery voltage class so we recommend the right series.

What should we include for a quote-ready RFQ?

Destination market, target model (kW), PV DC size/string plan, battery voltage window and target kWh, whether UPS/black-start is required, and any grid code/certification needs. Add quantity, timeline, and a one-line diagram if available.

Can this work on weak grids?

The series notes weak-grid tolerance (SCR < 1.2) and fast transfer behavior. Provide your site grid condition, generator policy (if any), and critical-load list so we scope the right protection and commissioning plan.
