FAQ

Yes, all the ATESS inverters can work in parallel. Parallel capability depends on the product series and configuration. The model comparison should identify supported quantities and maximum system power.

Consider peak load, continuous load, motor starting current, PV capacity, battery charge and discharge power, grid limits and future expansion.

A hybrid inverter manages energy from solar panels, batteries, the grid and connected loads, allowing power to be stored, used or exported according to the selected operating strategy.

Compare each energy storage system supplier on technical compatibility, documentation quality, delivery capability, regional support, spare-parts availability and lifecycle service, not just equipment price.

B2B buyers should ask the energy storage system manufacturer for verified specifications, compatible system architecture, certifications, lead time, warranty, commissioning scope, service coverage and project references.

Expansion depends on the selected battery energy storage system, PCS, voltage window and original system design. Plan future capacity during project engineering.

BESS power is sized in kW from peak demand and discharge requirements, while energy capacity in kWh is based on required duration and operating strategy.
