How many units can be paralleled?

Up to 9 units, giving 58,500 W in either single-phase or three-phase (415 Vac) configuration.

Does it support generator auto-start?

Yes. This model supports generator auto-start, and includes RS232 communication plus an external Wi-Fi module for app and cloud monitoring with OTA updates.

Is each unit 58.5 kW on its own?

No. 58,500 W is the total across 9 paralleled units. A single unit is in the 6.5 kW class.

How parallel expansion works

Each unit carries its own MPPT string (up to 9000 W), so nine units accept up to nine PV strings. Battery, output and control are interconnected. The system presents to the load as a single supply — 240 Vac single-phase, or 415 Vac three-phase.

Planning implications:

Battery bank scales with the system, not the unit. Nine units charging at up to 120 A each is a very large combined charge current. The battery bank must be sized so the combined charge current stays within the chemistry's 0.2C (lead-acid) or 0.5C (lithium) limit. This is the single most common sizing error on parallel systems.
Cable and protection are system-level. Three-phase output at 153.95 A per phase and single-phase at 265.9 A require appropriately rated switchgear.
Start with the load. Decide the target output (say 40 kW), divide by the single-unit class, then confirm the battery and PV support that many units.

Typical applications

Commercial and light-industrial sites needing three-phase supply with backup.
Rural electrification where a 415 Vac three-phase network is required.
Larger agricultural installations with multiple pumps and motors.
Sites with a standby generator where auto-start removes manual intervention.
