5kW GoodWe ESA Series Inverter with 6.65kW Solar and 16.64kWh Battery Storage Installed in Haynes

Installed in Haynes- 6112
This Haynes household doesn’t use a huge amount of power during the day, but evenings are a different story, with dinner, entertainment and everyone home at once. Rather than build a large solar array to chase maximum generation, the priority here was making sure whatever the panels produced got stored and used properly once the sun went down.
The System
The team installed a 5kW GoodWe ESA Series inverter paired with a 6.65kW solar system and a 16.64kWh battery storage setup. With more than double the battery capacity relative to the solar array, this system is weighted heavily toward storage, built to bank the day’s generation rather than spill it back to the grid.
The Install
Panels were fitted in a single tidy row along the roof’s northern face, keeping the install compact and the cabling minimal. The GoodWe battery was mounted in a brick alcove near the switchboard, with isolators and danger signage fitted as part of a fully compliant setup.
Benefits Worth Knowing About
A smaller solar array paired with a larger battery isn’t a downgrade, it’s a different way of getting the same result. Some things worth knowing:
- Evening power costs the same as day power. Time-of-use electricity tariffs mean power used at night is often billed at the highest rate. A battery this size shifts most of that cost back onto free daytime solar.
- Less equipment, less to maintain. A right-sized 6.65kW array means fewer panels on the roof to clean or service over the system’s lifetime, while still fully loading the battery on a sunny day.
- No noisy backup needed. With this much stored capacity, the home can ride out a short outage without reaching for a generator, quietly and automatically.
- Warranty coverage protects the investment. GoodWe’s battery warranty covers thousands of charge cycles, meaning this setup is built to perform for years, not just the first summer.
