Feature 01
Built for larger ESS rooms: higher battery voltage window (up to 1000 V) and industrial installation form factor.
Product Detail
WIT-50-100K-HU
Inverters
Growatt WIT 50–100 kW Hybrid Inverter
Higher-power three-phase hybrid inverter family (50/63/75/100 kW) designed for industrial and large C&I ESS sites—supports UPS/black start, up to 3 units parallel in off-grid mode, IP66 enclosure, and a higher-voltage battery window for larger energy rooms.
Key features
Feature 02
Supports three-unit parallel in off-grid mode, with 100% three-phase unbalanced load support noted for critical operations.
Feature 03
PV and MPPT architecture scales by model (50K/63K/75K/100K)—RFQ should name target model so we confirm the exact MPPT count and PV sizing limits.

Buyer FAQ
WIT 50 kW vs 100 kW—how to select?
Start with peak AC load (kW), target battery charge/discharge power (kW), and redundancy preference (one large unit vs multiple units). Include load profile and target tariff strategy (peak shaving vs backup) so we recommend the right model and ESS pairing.
What should we include in a quote-ready HU-series RFQ?
Destination market, target model (50/63/75/100kW), PV DC size and roof MPPT needs, battery voltage window (600–1000V) + target kWh, whether off-grid parallel/black-start is required, and any required certifications/grid code. Add quantity and timeline.
Why do some specs say “model dependent”?
The HU datasheet uses a multi-column table with MPPT counts, PV power limits, and charge/discharge values varying by kW model. We will confirm the exact values for your selected model when you provide the RFQ inputs.
