Description

Symmetrical 8-tracker routing for complex commercial roofs.

SAJ CH3-99.9K-T8 is a 99.9 kW commercial three-phase hybrid inverter with 8 independent MPPT trackers and 150 kWp solar intake, factory-capped at 99.9 kW (151.7 A) to streamline utility grid interconnection under 100 kW regulatory thresholds.

8 Independent 32 A MPPT Trackers (16 Strings)
Exceptional routing flexibility for sprawling industrial roofs, commercial carports, and ground mounts.
99.9 kW Grid-Optimized AC Output (151.7 A)
Sits precisely beneath 100 kW regulatory connection caps, simplifying utility grid interconnection approval.
150,000 Wp Solar PV Intake (150% Oversizing)
Pushes massive solar power directly into heavy factory loads and large-scale battery storage banks.
150 A High-Voltage Battery Interface (500–900 V)
Delivers high-speed DC charging and discharging to commercial battery banks for full facility peak shaving.

More product details

Sprawling logistics warehouses and commercial facilities with complex multi-pitch roofs suffer heavy mismatch losses if grouped on fewer trackers. The CH3-99.9K-T8 provides 8 independent 32 A MPPT trackers (Isc 40 A), optimizing 16 strings of 600W+ bifacial modules.

8 symmetrical MPPT channels allow dedicated tracking for multiple warehouse pitches with zero cross-string clipping.
Absorbs up to 150,000 W of solar generation, routing daytime power directly into industrial loads and 150 A storage racks.
Wide MPPT window (500–850 V) delivers peak electrical conversion efficiency under full continuous load.

Heavy commercial battery throughput with 99.9 kVA emergency power.

Transitioning into heavy commercial storage, the CH3-99.9K-T8 delivers 150 A continuous DC throughput across a wide 500–900 V window, allowing rapid cycling on large commercial battery containers (such as SAJ CB3-L261). Direct high-voltage pairing with SAJ CB2 and CB3 storage cabinets at up to 100 kW continuous DC power. 99.9 kVA continuous three-phase backup sustains commercial workshops and critical facility sub-panels in under 20 ms. IP65 heavy-duty cast-aluminum casing provides complete dust and high-pressure water protection (-30 to +60 °C).

CB3 is the listed battery.

CB3-L261 or CB3-M20 modules behind the CB3-HVC, 60 to 260 kWh per cluster, 200 A into 750-950 V LFP.

200 kWp of PV on a 99.9 kW hybrid.

200% oversizing puts 200 kWp on this 99.9 kW unit, so the roof can grow on this hybrid.

1500 V strings.

Longer runs than a 1000 V design, fewer DC home-runs on a commercial roof.

Technical data

Megawatt-scale commercial energy management engineered for grid-constrained industrial facilities.

8 MPPT trackers with 150 kWp solar intake and 99.9 kW continuous output.

Engineered for large commercial microgrids and grid-constrained industrial facilities, the CH3-99.9K-T8 features 8 independent MPPT trackers (16 string inputs) and 150,000 Wp solar intake.

Product questions

What is the main difference between the CH3-99.9K-T8 and the CH3-100K-T8?

Regulatory grid certification and nominal current limit (151.7 A vs 151.9 A). * CH3-99.9K-T8: Factory-capped at 99.9 kW / 151.7 A to comply with regional 100 kW grid connection limits. * CH3-100K-T8: Standard model rated at 100.0 kW / 151.9 A (110 kVA max apparent power) for unrestricted commercial grids.

What size AC circuit breaker and cable cross-section are required?

200 A or 250 A 3-pole industrial MCCB; 70 mm² to 95 mm² copper cable. The inverter has a maximum continuous AC output current of 151.7 A per phase (at 400 V three-phase). A 3-pole 200 A or 250 A industrial circuit breaker (MCCB) is standard on the AC distribution board.
