Description
SAJ CHS2-30K-T4-X: a three-phase all-in-one storage system with the CH2 hybrid inverter and the CB2 LiFePO4 battery in one cabinet, with 30 kW rated AC power and 4 MPPT trackers for up to 60,000 Wp of PV. The X in the name is the battery option: 57.3, 71.6, 85.9 or 100.3 kWh rated energy.
SAJ CHS2-30K-T4-X
30 kW rated AC power, 33,000 VA maximum apparent power: three-phase 3+N+PE at 380/400 V, 47.9 A maximum output current.
4 MPPT trackers with 2 strings each for up to 60,000 Wp: MPPT range 180–850 V, 1000 V maximum DC voltage, 22.5 A per string.
LiFePO4 battery in four options: 57.3, 71.6, 85.9 or 100.3 kWh rated energy, 51.5, 64.4, 77.3 or 90.2 kWh usable.
One cabinet of 1980 × 988 × 1065 mm (H × W × D) for indoor or outdoor installation: IP55, inverter IP66, cooled by an air conditioner, −30 to +50 °C.
Backup in 20 ms, generator input included.
The built-in STS switches between on-grid and off-grid operation in 20 ms. The backup output delivers up to 33,000 VA, and 45,000 VA for 5 s. A diesel generator connects to the GEN port without additional equipment, with up to 200 A input current; in single-unit operation the DRY.DO1 contact starts and stops it.
Expandable with up to three CB2 battery cabinets.
One CHS2 takes up to three further CB2 battery systems. For 2 to 10 CHS2 in parallel connection, the eManager-C1 Pro communication box is recommended.
SAJ
Inverter, battery and air conditioner in one cabinet.
The CHS2 combines the CH2 hybrid inverter and the CB2 battery system with its battery management system in one cabinet. The battery power cables are connected before delivery; on site the AC cables to the grid, the DC cables to the PV array and the communication cables are connected. The cabinet has type II surge protection on the AC and DC side, CO and fire detection and cabinet-level fire protection. Arc-fault detection (AFCI) is built in and is enabled in the elekeeper app.

Project fit
Where this model fits.
Scenarios that show which projects the SAJ CHS2-30K-T4-X belongs in, and the limits behind our engineers' recommendation.
Supermarkets, farms and small factories with up to 60 kWp of PV
Sites with a three-phase 380/400 V connection that use their PV power themselves, shift it by time of use and keep backup loads supplied in a grid outage.
4 MPPT trackers take up to 60,000 Wp; the cabinet stands on the ground indoors or outdoors and runs in self-consumption, time-of-use and backup mode.
- Grid connection 3+N+PE, 380/400 V; string voltage within the 180–850 V MPPT range and below 1000 V; 2 strings per tracker with at most 22.5 A per string; ambient temperature −30 to +50 °C, with derating from 45 °C; flat ground with a load-bearing capacity of 1.5 t.
