Configuration 2
The SAJ CB3 series; the battery input accepts 750 to 950 V LFP clusters at up to 200 A.
- Rack build: CB3-M20 stackable 20.096 kWh modules with a CB3-HVC control module per cluster; the HVC is required and is a separate order code.
- Cabinet build: the CB3-L261 liquid-cooled cabinet at 261 kWh.
- Cluster range: 60 to 260 kWh per cluster, per SAJ's CH3 and CB3 datasheet.
- Current: maximum charging and discharging current is 200 A on every CH3 rating, from the 75 kW to the 125 kW model.
The split is PV string count and AC power; the chassis is the same 135 kg, IP66 unit across the range.
- T6 models: CH3-75K-T6 and CH3-80K-T6, 6 MPPT with 2 strings each, PV arrays up to 150 and 160 kWp.
- T8 models: CH3-99.9K-T8, 100K-T8, 110K-T8 and 125K-T8, 8 MPPT with 2 strings each, PV arrays up to 200, 200, 220 and 250 kWp.
- Grid-limited connections: the CH3-99.9K-T8 holds output at 99.9 kVA where the connection must stay under 100 kVA; the 100K-T8 is the full 100 kVA unit.
- Oversizing: every rating accepts a PV array of about twice its AC power, for example 250 kWp on the 125 kW model.
Installation & wiring 1
Higher string voltage moves the same power at lower current, which cuts DC-side cost across the array.
- MPPT window: 300 to 1500 V, with a 1050 V rated DC voltage and 1500 V maximum; strings start at 400 V.
- Current limits: 40 A maximum DC input current with a 55 A short-circuit rating, 2 strings per tracker, per SAJ's datasheet.
- Cabling: a 1500 V string carries the same power at lower current than a 1000 V string, so DC cable cross-section, combiner count and DC-side losses all fall.
- Protection: an integrated string-level disconnector, Type II surge protection on DC and AC, and optional AFCI.
Operation & warranty 2
Backup carries full rated power, and both the transfer switch and the EMS are integrated in the inverter.
- Backup rating: maximum backup output equals the AC rating, 75 to 125 kVA across the family.
- Overload headroom: 1.1 times rated power continuously and 1.55 times rated for 1 s in backup, per SAJ.
- Generator port: accepts up to twice the AC rating, for example 150 kW at 227.8 A on the 75 kW unit and 250 kW at 379.8 A on the 125 kW unit.
- No external STS: transfer switching and energy management are built in; the generator lands on a port on the inverter.
SAJ backs the CH3 with a 5 or 10 year warranty and rates it for a wide ambient window.
- Warranty: 5 or 10 years per SAJ's datasheet; state the required term in your request.
- Ambient: -30 to +60 C operation, with derating between 45 and 50 C, up to 3000 m altitude, smart air cooling, IP66 enclosure.
- Efficiency: SAJ publishes at least 98 percent maximum efficiency, at least 97.5 percent Euro efficiency, and at least 98 percent battery-to-AC efficiency as minimum figures.
- Monitoring: LED indicators plus WLAN and app monitoring, per SAJ's datasheet.
Availability & compliance 1
SAJ lists the IEC set below and marks the current CH3 datasheet as preliminary; confirm the certificate set with the quote before contract.
- Standards: IEC 61727, IEC 62116, IEC 62109-1 and -2, and EN 61000-6-2 and -4, per SAJ.
- Preliminary status: SAJ states the datasheet parameters are for reference; we verify the values against the release documentation before contract.
- Country grid codes: certificates for a specific installation country are not printed in our current data set. Name the country in your request and we confirm the applicable set in writing with the quote.
