Retrofits: What You Need to Know
Adding a battery to your existing solar system can cost from $9,500 to $16,000, depending on:
1. Whether your current inverter is hybrid-compatible
2. Battery size and brand
3. Installation requirements (wall mounts, switchboard upgrades)
In many cases, retrofitting requires an inverter upgrade, which Powermate can handle in-house as part of our full compliance and system performance review.
