ESS GTL 200kW+209kWh Integrated Solar & Storage System

Q: What does the ESS GTL 200kW+209kWh 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.

Q: How are critical loads protected during an outage?

The built-in transfer unit switches in ≤10 ms; off-grid output is — with 100 % unbalanced-load capability.

Q: 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.

Q: How should the PV array be sized?

The MPPT window is — with — maximum DC input; string open-circuit voltage must stay below the stated limit.

Q: 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.

概要

ESS GTL 200kW+209kWh Integrated Solar & Storage System pairs a 200kW grid-tied inverter with 209kWh LiFePO₄ storage; MPPT window —, transfer to island within ≤10 ms, liquid cooling and IP54. It serves PV self-consumption, peak shaving and critical-load backup in parks and distribution areas.

製品の特長

Rated power 200kW with 209kWh LiFePO₄ storage
On/off-grid transfer within ≤10 ms
MPPT window —, max. DC input —
All-in-one cabinet build, liquid cooling, IP54 enclosure

製品説明

The ESS GTL series integrates the PV inverter, the liquid 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 GTL 200kW+209kWh runs at 655.2VDC with roughly 209kWh usable, measures 1370×1120×1850mm and weighs about 1890kg. 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.
