製品説明
The ESS HVA series integrates the PV inverter, the air cooling LiFePO₄ battery and the on/off-grid transfer unit in a single cabinet — covering self-consumption, peak shaving and backup power. Wiring and commissioning are done inside the cabinet, so site work is limited to positioning and paralleling.
The ESS HVA 50kW+105kWh runs at 512VDC with roughly 105kWh usable, measures 800×1200×1850mm and weighs about 1150kg. Each cabinet is wired, insulation-tested and function-tested before shipment, so it can be specified and ordered once the load list and local grid requirements are confirmed.

製品FAQ
What does the ESS HVA 50kW+105kWh system solve?
It bundles the PV inverter, battery and on/off-grid transfer into one cabinet, addressing four pain points: weak self-consumption, peak-valley arbitrage, limited transformer capacity and backup for critical loads — with far less site integration work.
How are critical loads protected during an outage?
The built-in transfer unit switches in ≤10ms; off-grid output is 50kVA with 100% unbalanced-load capability.
Can units be paralleled or the battery extended?
Yes, both parallel operation and battery extension are supported. The number of parallel units depends on busbar rating, protective devices and the local grid-connection permit, and is confirmed in the project single-line diagram.
How should the PV array be sized?
The MPPT window is 200V~800V with 38.4kW+38.4kW maximum DC input; string open-circuit voltage must stay below 850V.
Lead time and customisation?
Standard batches ship in 15-30 days; volume orders and customised models follow the contract. Appearance, protocols, grid-compliance packages and monitoring-platform interfaces can be adapted.
