SAJ CB2-57.3-HV5 (57.3 kWh C&I battery cabinet)
SAJ CB2-57.3-HV5 is the 57.3 kWh step of the CB2 battery cabinet used by the CHS2 commercial storage line: 4 LiFePO4 modules and one control module in a closed, air-conditioned IP55 cabinet, rated 51.5 kWh usable at 28.6 kW.
- 57.3 kWh rated and 51.5 kWh usable for the whole cabinet — SAJ's own figure, not a per-module number multiplied up.
- 4 x CBU2-14.33-HV5 LFP modules plus a CBC2-HV5 control module, installed and closed at the factory.
- Integrated air conditioner and IP55 enclosure, ground-mounted, -30 to +50 °C and up to 2000 m.
- 280 Ah cells at 150 A maximum charge and discharge current, CAN to the inverter or EMS.

Every figure comes straight from the manufacturer's official datasheet.
Configuration 2
One ground-mounted battery cabinet, populated and closed at the factory.
- 4 x CBU2-14.33-HV5 LFP battery modules, 14.33 kWh each, 115 kg each.
- 1 x CBC2-HV5 control module, 28 kg.
- Enclosure: 1980 x 988 x 1065 mm, IP55, air-conditioner cooled, 960 kg complete.
- Rated 57.3 kWh, 51.5 kWh usable — SAJ publishes the usable figure for the whole cabinet, not per module.
CHS2 is the same cabinet with the inverter built in; CB2 is the battery side on its own.
- CHS2-29.9K-T4-X, CHS2-30K-T4-X, CHS2-50K-T6-X each contain a CH2 inverter (76 kg, 630 x 630 x 290 mm) plus one of these four CB2 cabinets.
- Same footprint: 1980 x 988 x 1065 mm either way — the CHS2 weight is the CB2 weight plus the inverter section.
- Order CB2 on its own when the inverter side is already specified, or to fix the storage capacity independently of the inverter rating.
Installation & wiring 2
SAJ publishes CB2 inside the CHS2 system document, alongside the CH2 inverter models CH2-29.9K-T4, CH2-30K-T4 and CH2-50K-T6.
- Cabinet ratings: 57.3 kWh at 28.6 kW, 150 A maximum charge and discharge current.
- Battery bus: the CHS2 inverter side accepts 180 to 800 V; this cabinet sits inside that window.
- Confirm the pairing on the quote. The datasheet publishes the cabinet's own ratings; which inverter and how many cabinets a site takes is set by the project, so we check it against your single-line before shipping.
Outdoors or in a plant room, on a prepared slab.
- IP55, ground-mounted, with an integrated air conditioner rather than forced-air cooling.
- -30 to +50 °C ambient, 5 to 95 percent relative humidity non-condensing, up to 2000 m altitude.
- 960 kg — the slab, access route and lifting plan need to carry it; we include the cabinet drawing with the quote.
Availability & compliance 1
One cabinet, one pallet position, freight rather than parcel.
- ADR: lithium cells ship under dangerous-goods rules; the freight quote reflects that.
- Arrives populated: modules and control module are installed at the factory, so site work is placement, DC and communications termination.
- Lead time is confirmed after order — we do not publish a stock figure we cannot stand behind.
