From a 15 kWh tower in a Dutch semi-detached house to a 5 MWh container behind a Polish substation — the same cell platform, the same documentation discipline.
Grid-connected BESS for peak shaving, capacity firming and islanding. Containerised platforms with smart EMS, on/off-grid switching and IEC 104 to the dispatch system.
Typical fit — Containerised BESS 5 MWh, mobile/trailer 430–783 kWh
Load shifting, demand-charge control and UPS-grade backup for plants with spiky loads. Liquid-cooled cabinets sized per transformer and per shift pattern.
Typical fit — Liquid-cooled cabinet 232 kWh, PV-storage all-in-one 261 kWh
Standby power and 48 V rack modules for cold-aisle and telecom sites. Indoor IP20 racks, stackable to 15 units, with BMS telemetry over Modbus or SNMP gateways.
Typical fit — Rack modular 51.2 V, lead-acid drop-in
PV self-consumption, backup and off-grid. Tower stacks from 15 to 60 kWh, or the single-phase all-in-one where the meter cupboard has no room for a separate inverter.
Typical fit — Residential tower, 5–40 kWh AIO
Private-label packs, custom BMS firmware and enclosures built to your drawing. Neutral units for first-article approval, then series production under your nameplate.
Typical fit — 12 V to 1000 V class, 4 Ah to MWh
IP68 packs, yacht and boat systems, underwater hot-swap. This is where our sealing and thermal engineering comes from — see below.
Typical fit — 96 V / 30 kWh marine pack, 166 V truck pack
Water applications have been in mass production since 2014, and they are where our sealing and thermal engineering comes from — the same discipline that holds an outdoor C&I cabinet at IP55 from −35 to +55 °C.
Relevant where a storage project includes harbour, fleet or offshore infrastructure, or where the enclosure has to survive a salt-laden atmosphere.
| Capability | Value |
|---|---|
| Max waterproof depth | 350 m |
| Continuous discharge | 500 A |
| Max discharge rate | 80 C |
| Low-temperature operation | −40 °C |
Connector design that cannot arc when wet — replaced in the water, without surfacing.
High-rate discharge without the pack walking out of its cradle.
Every joint validated by first-article pull test and in-line CCD inspection, from cell to pack.
Early warning before a seal failure becomes a warranty claim.
Yacht and boat — 96 V / 30.14 kWh marine pack (1P30S, CAN); 76.8 V / 11.5 kWh IP67 pack with GPS and 4G monitoring.
Underwater drones — IP68, 10–350 m, hot-swap at 5–50 m.
Mobility — 51.2–72 V LFP packs; 166.4 V / 46.6 kWh liquid-cooled truck pack.
Most first quotes come back wrong because one of these is missing. Send them in any format — a sentence per line is fine.
The DC window your PCS or inverter accepts.
kWh required, kW required, and the C-rate you will actually run.
Cycles per day, depth of discharge, and whether the load is a peak or a plateau.
Indoor or outdoor, ambient range, altitude, salt or dust exposure.
And if grid-tied, which country code the installer is certifying against.
Which certificates the tender actually requires, not which ones are nice to have.
Voltage window, energy, power and C-rate, duty profile, installation environment, destination country. That is enough for a first proposal.
