200,000 W Massive Solar PV Intake (200%)
Massive 8-MPPT capacity captures immense rooftop solar power to run heavy factory loads and rapid battery charging.
8 Independent 30 A MPPT Channels (16 Strings)
Accommodates modern high-current bifacial panels across sprawling industrial roofs without current throttling.
100 A High-Voltage Battery Interface
Drives large commercial storage containers at full speed for dynamic demand charge management and peak shaving.
More product details
Utility connection rules frequently require plant capacity to remain strictly under 100 kVA. Eight MPPT circuits absorb up to 200 kW of DC generation without exceeding threshold caps. Sixteen strings distribute massive solar production across a single wall-mounted inverter.

Holds grid throughput precisely at 99.99 kVA.
AC output stays strictly capped at 99.99 kVA to satisfy regional grid interconnection limits. Two high-voltage battery ports support rapid storage charging from excess solar. Intelligent cooling fans vent the 97 kg die-cast enclosure. An IP66 weatherproof chassis operates continuously from minus 35 to 60 C.
Holds 99.99 kVA compliant AC throughput
Rated active power is 99.99 kW with apparent power locked at 99.99 kVA. This meets strict grid threshold regulations without extra limiting hardware.
Takes 200 kW across eight MPPTs
Eight MPPT trackers take 42 A each with 2 strings per channel. The 160 to 950 V MPPT window maximizes energy yield from large multi-pitch roofs.
Pairs dual 300 to 800 V battery banks
Two battery inputs accept high-voltage storage with a nominal 600 V bus. CAN bus integration coordinates balanced charging across both ports.
