Powerful Value
Efficient and reliable performance
One of the standout features of the GoodWe ESA series is its fast charging and discharging capability. It has been engineered to charge efficiently without throttling performance, and discharge quickly to deliver more power output with fewer battery modules.
Battery Rebate Now Available
The battery rebate reduces again at the end of December. Install your battery now for the maximum discount.
The battery rebate is tiered based on the battery storage capacity. The STC factor is the number used to calculate your rebate. The more STCs that apply, the bigger the rebate.
0–14 kWh:
Full rebate (100% of STC factor applies)
14–28 kWh:
60% of the STC factor applies
28–50 kWh:
15% of the STC factor applies

Designed by electricians, not sales people
We design superior systems that perform better and look more beautiful.
Omzen Solar doesn’t just sell you a battery, we design and install battery systems that perform to the very highest standards. As qualified electricians, we assess your existing electrical system in detail to ensure your new battery system is designed to account for the nuances of the property’s wiring.
What to be aware of
Too often, systems are designed by sales reps who don’t have the electrical qualifications to understand the complexity of a home’s existing wiring. Without the technical expertise of a qualified electrician they can’t foresee future implications and inadvertently design inferior systems.
Alternatively, systems are designed with a ‘path of least resistance’ mentality to cut corners and reduce the subcontractor installation cost.
Ultimately customers are hit with unexpected costs to make a system compatible. Or left with under-performing systems and messy installs by subcontractors that cut corners to hide mistakes in the design or rush to get onto the next job.
