TAIGA CH-28KW-55KW-208V is a hybrid inverter for commercial solar and storage. 28 to 55 kW output across four power tiers (28, 35, 40, 55 kW), 208/220V three-phase, IP66 outdoor-rated enclosure. Supports up to 6 units in parallel for a combined 330 kW. Built-in UPS with black start capability keeps loads running through grid outages without an external transfer switch. Compatible with high-voltage lithium-ion battery banks (380 to 650V) and can also work with lead-acid batteries. The data logger is built in for plug-and-play monitoring; optional connects the system to the Gietron cloud platform for remote management and firmware updates.
