Product Description
SP375HAG2 and SP500HAG2: 375 kW and 500 kW hybrid cabinet options
The SP375/500HAG2 family combines PV conversion, battery PCS and microgrid transfer equipment in one cabinet. The two configurations are marketed in the 375 kW and 500 kW power classes. The published on-grid apparent-power ratings are 375 kVA and 500 kVA; verify rated active power, power factor and the final nameplate for the ordered version.
What changes between the 375 and 500 models?
Both models use the same integrated architecture: PCS, MPPT, EMS, PCM transfer switch and AC/DC distribution. The documented PV input is 120 kW × 3 for the 375 configuration and 120 kW × 4 for the 500 configuration. Battery current, AC current and the PV channel count differ by model; select from the matching datasheet rather than treating one cabinet as a software-only power upgrade.
System topology
PV strings → cabinet MPPT → DC bus ↔ PCS ↔ AC bus → loads / grid. Batteries connect to the DC bus. A diesel generator connects to the designed AC source interface; PCM transfer equipment handles the configured grid/off-grid source transition. The family data lists no built-in isolation transformer; a project that requires one must include an appropriately sized external transformer.
Operating modes
- Grid-connected PV self-consumption and surplus export where enabled and permitted.
- Battery charging from available PV and discharge for configured load support or peak management.
- Off-grid operation with PCS forming/supporting the AC bus when the selected controls and system design allow it.
- Diesel hybrid operation, with generator dispatch and battery charging subject to EMS settings and generator limits.
The product data lists active transfer at 0 ms and passive transfer below 20 ms. The actual sequence depends on control mode, upstream protection and site commissioning.
Verified selection data
- Battery rated range: 680–900 V; maximum 950 V.
- PV input: 120 kW × 3 / 120 kW × 4; maximum PV voltage 950 V.
- Grid-tied apparent power: 375 kVA / 500 kVA; grid voltage 400/230 V, three-phase four-wire.
- Off-grid maximum apparent output: 412.5 kVA / 550 kVA (confirm duty and overload conditions).
- Maximum 3 units in parallel for the specified family configuration.
- Protection is listed as IP54/IP20 by configuration; confirm the ordered enclosure.
Applications and limits
Consider the 375 model where the project needs the integrated PV-storage functions at the lower power class; consider the 500 model for a higher load or more PV input channels. Both can suit PV-battery-diesel microgrids, construction sites, oilfields and backup power. Confirm active power at the required power factor, motor-starting demand, battery current, transformer requirements, grid code and the parallel-control version.
Documents and related equipment
Request the matching 375 or 500 datasheet, wiring diagram, transfer sequence and available certificates for the supplied version. Compare with SP250HAG2T 250 kW for a transformer-integrated cabinet or LEONA-B750K 750 kW PCS for a higher-power PCS-led design.

Product FAQ
What is the configuration difference between SP375HAG2 and SP500HAG2?
The documented PV input differs: 120 kW × 3 for SP375HAG2 and 120 kW × 4 for SP500HAG2. The on-grid apparent-power ratings are 375 kVA and 500 kVA. Confirm active power and power factor for the exact configuration.
Can the 375 kW and 500 kW cabinets connect PV, batteries and a diesel generator?
Yes. The family integrates PV MPPT and PCS, and supports battery, PV and diesel connection. Grid interface, protection and operating sequence must follow the project drawings.
How many SP375/500HAG2 cabinets can be paralleled?
The product data specifies up to three units for the family. Confirm controller compatibility and the permitted combination before designing a multi-cabinet system.
Does the cabinet include an isolation transformer?
The published data lists no built-in isolation transformer for this family. Add an external transformer if the site voltage or grounding design requires one.
Are 375 kW / 500 kW the same as 375 kVA / 500 kVA?
No. kW is active power and kVA is apparent power. The published on-grid figures are 375/500 kVA; obtain the final active-power rating at the required power factor from the project datasheet.
