Who Battery Storage Is For
Battery storage in Waikato is for anyone who already has, or is planning, a solar system and wants to get more value from the energy they generate. If you're exporting surplus solar for a low feed-in rate and buying it back at night at a higher rate, a battery lets you keep more of that energy on-site.
It's also for homes, businesses and farms that value resilience. With the right setup, a battery can keep essential loads running during a grid outage. Across Hamilton and the Waikato, we help property owners decide whether storage makes sense now, or whether a battery-ready solar system is the better starting point.
The Benefits of Battery Storage
Use Your Solar Around the Clock
Store the surplus you generate during the day and use it in the evening or early morning, increasing how much of your own solar you consume on-site.
Protection During Outages
With the right system, battery storage can keep essential loads running during a grid outage, valuable for homes, businesses and farms alike.
Manage Demand Charges
For commercial and farm connections, stored energy can help flatten peak demand, which can reduce demand-based charges on your bill.
Add Storage When It Suits You
Every solar system we install is designed battery-ready. Start with solar now and add storage when prices fall or your needs change.
Right-Sized, Not Over-Sold
We size battery storage to your actual usage and goals. We won't sell you more storage than makes economic sense for your property.

Common Questions
Do I need a battery to go solar?
No. Many homes, businesses and farms achieve strong savings through direct daytime self-consumption alone. Batteries are an add-on that improves self-consumption and resilience, not a requirement.
How much battery storage do I need?
It depends on your evening and overnight usage, and whether you want backup during outages. We size storage to your actual load profile, not a one-size-fits-all package.
Can I add a battery to my existing solar system?
In many cases, yes. We can assess your current system and advise on compatible battery options, including any inverter or wiring changes required.
How long do solar batteries last?
Most modern lithium batteries come with warranties of around 10 years. We'll talk you through lifespan, warranties and realistic performance during your assessment.
Will a battery run my whole house or farm during an outage?
That depends on the battery capacity and which loads you want to back up. We design backup configurations around the circuits that matter most to you.
