Application / Residential
Residential Solar Storage & Backup
A home battery should be designed around measured loads, solar production, critical circuits, desired outage duration, and inverter compatibility.
What the residential solar and backup solution must accomplish
A home battery should be designed around measured loads, solar production, critical circuits, desired outage duration, and inverter compatibility.
Monthly utility bills do not show the timing, surge, or criticality of household loads. Whole-home backup and critical-load backup are different designs, while photovoltaic output, export rules, seasonal conditions, and installation space affect the practical battery size.
Recommended system-design approach
Create a critical-load schedule, measure or estimate each load's power and daily energy, then model the solar and grid operating modes. Select rack, stacked, or wall-mounted batteries only after the inverter, communications, energy, and installation requirements are known.
- Critical and non-critical circuits, continuous power, and motor-start surge
- Daily energy, desired outage duration, solar production, and recharge time
- Inverter voltage, communications, approved battery count, and changeover design
- Indoor or outdoor location, wall or floor structure, clearances, and cable routing
- Local electrical, fire, permitting, and utility interconnection requirements
How to prepare a technical brief
A useful technical brief describes the operating problem before naming a product. Follow the steps below so the proposal can be sized against real loads, constraints, and operating priorities.
- List loads by watts, hours per day, surge demand, and backup priority.
- Choose critical-load or whole-home scope before selecting capacity.
- Confirm inverter and battery communications compatibility.
- Compare rack, stacked, and wall formats against the installation space.

Home Battery Sizing
Size a home battery from the loads that must run, their coincident and starting power, required backup hours, usable-energy assumptions, recharge opportunity, and the inverter's supported battery configuration.

Home Battery Formats
Rack, stacked, and wall-mounted batteries mainly differ in mechanical format, expansion method, service access, footprint, cable routing, and integration. Energy needs and inverter compatibility remain the first filters.

Solar Battery Decision Guide
A solar battery is worth evaluating when it supports a defined objective that can be modeled from interval loads, solar production, outage needs, export limits, tariffs, and operating constraints.
Read guide →Frequently asked questions
What buyers ask before specifying a battery system
How is a battery sized for a solar project?
Sizing starts with interval load data, photovoltaic production, desired backup loads, outage duration, export limits, tariff periods, and the operating objective. Oversizing from monthly consumption alone can produce a poor technical and commercial result.
Can a home battery back up every household load?
Only if the inverter power, battery energy, surge requirement, wiring, and changeover design support those loads. Critical-load backup and whole-home backup are different designs and should be specified separately.
How do rack-mounted, stacked, and wall-mounted home batteries differ?
They primarily differ in installation format, expansion method, service access, footprint, and system integration. Select the format after checking space, inverter compatibility, required energy, cable routing, and local installation rules.
Is nameplate energy the same as usable energy?
Not necessarily. Usable energy depends on the permitted state-of-charge window, operating conditions, conversion losses, control strategy, and project limits. Ask for both nominal and usable values in the final proposal.
