Description

GoodWe ESA 20kWh Battery Storage All-In-One System combines inverter, battery, and intelligent energy management in a three-phase all-in-one high-voltage (HV) storage system. As a pre-wired, modular solution, it is suitable for private households and small commercial operations looking to efficiently store their solar power and reduce electricity costs. The GoodWe battery storage of the ESA series can be expanded up to a total of 108 kWh, covering growing energy needs as well.

Your Benefits at a Glance

Compact all-in-one design: Inverter, battery storage, and energy management are pre-wired into one system, speeding up commissioning.
Reliable backup power: Thanks to the dual-port design and a switchover time of under 4 ms, your home stays powered even during a grid outage.
High safety: Advanced 6-level protection, AI-powered AFCI 3.0, and IP66 ensure reliable operation.
Cold-weather robustness: The integrated heating mode ensures safe performance even at temperatures down to -20 °C.

The System in Detail

The Power Module (Inverter)

The three-phase power module controls the interaction between photovoltaics, battery storage, and the household grid. It supports up to 200 % DC oversizing, operates quietly with intelligent fan cooling at a noise level of up to 30 dB, and is prepared for AI-driven energy management for dynamic tariff optimization. The dual-port design enables whole-home backup power.

The Battery Storage

The storage uses proven LFP (LiFePO4) technology, known for its long lifespan and high safety. Each battery module features an integrated heater as well as an integrated aerosol fire suppression system. The modular design allows flexible combination of batteries with different capacities and expansion of the GoodWe battery storage for higher self-consumption. Please refer to the order for the specific module configuration for approximately 20 kWh [PLEASE CHECK].
