- What's the difference between a whole-home battery and a backup battery?
- A whole-home system is sized to carry most or all of a home's circuits during an outage. A backup battery is typically smaller and is sized to keep essential circuits — refrigerator, lighting, networking, a few outlets — running.
- Can I install one of these myself?
- Most battery systems in this category involve electrical work that requires a licensed electrician and, in many jurisdictions, a permit and inspection. We sell the equipment; installation is handled by a licensed professional you choose.
- Do battery capacities listed on product pages reflect real-world performance?
- We label every specification by how confident we are in it — verified against manufacturer documentation, as provided by the supplier, estimated, or missing — so you can judge how much to rely on each number before you buy.
- Can I expand a battery system later?
- Some systems support add-on modules to increase capacity after your initial purchase. Check the Expandability specification on a product's page for compatibility details.
- How is shipping handled for large battery systems?
- Shipping details, carrier, and any freight requirements are shown on each product page under Shipping Information before you check out.
- Do you offer financing or installer matching?
- No — Ironwatt is a retail equipment seller. We don't arrange installation appointments or financing; you choose and pay your own licensed installer.
