Description
SAJ H2-20K-T3 is a three-phase hybrid inverter with 20,000 W rated AC power and 22,000 VA maximum apparent power. It has three MPPTs for up to 40,000 Wp of PV, two battery inputs for 180–800 V LiFePO4 batteries and a backup output.
SAJ H2-20K-T3
PV array power up to 40,000 Wp (STC) on three MPPTs with two strings each.
40 A maximum DC input current and 50 A maximum short-circuit current per MPPT.
Backup output with 20,000 VA and a peak of 30,000 VA for 3 s.
Supplied with the eSolar AIO3 communication module, a smart meter and three current transformers.
Three MPPTs with 40 A each.
Each of the three MPPTs takes two strings, with 40 A maximum DC input current and 50 A maximum short-circuit current per MPPT. The MPPT voltage range is 180–900 V, the maximum DC voltage 1000 V and the start voltage 180 V.
Backup output with a switch-over time of ≤ 20 ms.
The backup output supplies up to 20,000 VA and a peak apparent power of 30,000 VA for 3 s; the switch-over time to backup is ≤ 20 ms. The backup function needs a properly grounded backup PE line and earthing bar.
SAJ
Two battery inputs for 180–800 V.
The inverter has two battery inputs (BAT1 and BAT2) for LiFePO4 batteries with a battery voltage range of 180–800 V and a maximum charge and discharge current of 50 A. The SAJ B2 high-voltage battery is used as a set with the H2; the B2's own maximum charge and discharge current is 30 A.

SAJ's B2 datasheet names B2-5.0 to B2-25.0 as one to five BU2-5.0 modules with one BC2-HV1 control module, and SAJ's B2 manual (V1.2, PDF p5) says the B2 can only be used as a set with SAJ's H2 high voltage series storage inverter. The listing does not cover the one-module B2-5.0, whose operating voltage lies below the H2 T3's battery voltage range. SAJ's B2 datasheet gives 179.2 to 230.4 V for the two-module B2-10.0; the H2 T3 manual's battery voltage range begins at 180 V.
