How to Choose a Modular Home Battery
- Start with the load profile. Review daily energy consumption, peak loads, essential circuits, and the expected backup duration. A larger nameplate battery is not automatically the best match.
- Compare usable capacity and power. Capacity describes stored energy, while continuous and peak power determine which appliances can run simultaneously.
- Confirm inverter compatibility. Check whether the battery is designed for the proposed inverter, whether communications hardware is required, and whether the system supports AC-coupled or DC-coupled installation.
- Check expansion limits. Ask how many battery modules can be added, whether expansion must occur within a defined time, and whether mixed module ages or models are permitted.
- Review safety and compliance documents. Confirm the relevant electrical, fire, transport, and grid-interconnection requirements for the installation country and region.
- Examine warranty language. Compare years, throughput or cycle limits, retained capacity, exclusions, labor coverage, and the party responsible for warranty service.
- Assess installation and service. A technically suitable battery may be impractical if qualified installers, replacement parts, commissioning support, or local service are unavailable.
- Consider monitoring and controls. Look for clear information about app access, energy data, alerts, remote updates, backup settings, and data connectivity.
- Calculate total installed cost. Include the battery, inverter, gateway, protection equipment, labor, permits, shipping, taxes, and any required changes to the main electrical panel.
