Products and specifications

Five platforms from 5.2 kWh modules to 5 MWh containerised systems. Where a figure depends on the exact configuration it is marked accordingly and confirmed in the signed technical annex — we do not publish a number we cannot evidence with a test report.

PV-storage all-in-one cabinet with PCS, MPPT, STS, EMS and BMS
HYBRID

PV-storage all-in-one

261 kWh / 125 kW · 768 V

PCS, MPPT, STS, EMS and BMS integrated in a single cabinet, with on/off-grid switching. 125 kW per cabinet at 768 V; three cabinets paralleled make a 375 kW block. It reduces the electrical room to a single line item for EPCs.

Measurement conditions. Cycle life is quoted at rated depth of discharge and 25 °C unless the technical annex states otherwise. Efficiency is quoted at the DC terminals at 25 °C and 50 % load — AC-to-AC system efficiency including auxiliary power is stated separately per project, because it depends on the PCS and HVAC selection. Operating temperature range refers to discharge; charging below 0 °C requires the heating film option.

OEM / private label

Cabinet colour, nameplate, connector, language — yours.

Enclosure rating, display language and documentation set are customer-specified. OEM nameplates and private-label manuals are available, and a neutral, unbranded unit is supplied for first-article approval before series production.

Tell us the duty cycle. We will send the datasheet.

Voltage window, energy, power and C-rate, duty profile, installation environment, destination country. That is enough for a first proposal.
