SolarEdge Home Battery

The SolarEdge Home Battery is a DC-coupled lithium-ion battery storage system designed to work natively with the SolarEdge Home Hub Inverter.

Key specifications: - Capacity per unit: 9.7 kWh usable - Scalability: Up to 3 batteries per inverter (29.1 kWh total) - Continuous power output: 5 kW - Peak power output: 7.5 kW - DC coupling efficiency: >99% when charging from solar - Warranty: 10 years Because the SolarEdge battery is DC-coupled to the inverter - rather than connected on the AC side - it charges directly from the solar panels' DC output without an intermediate DC-to-AC conversion.

This is more efficient than AC-coupled systems and simplifies the overall installation. During a grid outage, the battery and any available solar production power your home's protected loads. The SolarEdge ONE EMS can also schedule overnight charging from the grid during cheap off-peak hours for use during expensive peak periods.

Generally, no - SolarEdge inverters are designed to work with SolarEdge Power Optimizers and cannot be directly substituted into a system designed around a different inverter brand.

However, you can expand an existing SolarEdge system by adding more panels with compatible optimizers and potentially upgrading the inverter if additional capacity is needed. If you have an older SolarEdge system and want to add battery storage, you will need to assess whether your existing inverter is battery-ready or needs to be replaced with a Home Hub. SolarEdge's online compatibility tools and your installer can help assess upgrade paths.

Note that older SolarEdge HD-Wave inverters can often be upgraded to work with the SolarEdge Home Battery via a firmware update or hardware retrofit, depending on the model.

The SolarEdge system achieves an overall efficiency of approximately 98%, combining the Power Optimizer efficiency (~98.8%) with the string inverter efficiency (~98.3%).

This compares favorably to Enphase microinverters (~97% overall) and is competitive with the best conventional string inverters. For DC-coupled battery charging (using the Home Hub Inverter), efficiency exceeds 99% because solar energy flows directly from the DC optimizers to the battery without a DC-to-AC conversion.

This is notably more efficient than AC-coupled battery systems, which must convert DC solar to AC and then back to DC for battery storage.

SolarEdge ONE is SolarEdge's AI-based home energy management system (EMS). It acts as the intelligence layer on top of the SolarEdge hardware ecosystem, automatically optimizing when and how your home uses, stores, and sells solar energy based on your utility's rate schedule, weather forecasts, battery state, and personal preferences.

SolarEdge ONE integrates with the SolarEdge Home Battery, SolarEdge EV Charger, compatible heat pumps (including Vaillant), smart home switches, and third-party devices. It can automatically divert excess solar to charge your EV, pre-heat or pre-cool your home using solar before peak rate hours, and enable the Weather Guard feature, which pre-charges your battery to full before a predicted storm.

SolarEdge ONE is managed through the mySolarEdge app (available for iOS and Android, last updated January 25, 2026) and the web-based monitoring portal.

A SolarEdge residential installation follows these general steps:

1. A certified installer designs the system using SolarEdge's Designer software tool, specifying panel layout, optimizer models, inverter size, and wiring configuration.
2. Permits are pulled from the local authority having jurisdiction (AHJ).
3. Panels and optimizers are mounted on the roof - each optimizer is physically attached to the back of or near each panel.
4. The central inverter and Gateway are mounted on a wall (typically in the garage or utility room).
5. DC wiring from the optimizer strings runs to the inverter.
6. The inverter connects to the main electrical panel.
7.  After a utility inspection, the system is activated and commissioned in the SolarEdge monitoring platform. The full process from contract signing to activation typically takes 4-12 weeks, with most of that time spent waiting for permits and utility approval rather than actual installation work.

SolarEdge warranties vary by component: - Inverter (Home Hub): Standard 12-year warranty, extendable to 20 or 25 years at additional cost through SolarEdge's warranty extension program.

You can purchase extensions at any time during the original warranty period. - Power Optimizers: 25-year warranty (standard, no extension needed). - SolarEdge Home Battery: 10-year warranty. The inverter warranty covers defects in materials and workmanship. SolarEdge typically ships a replacement unit within 48 hours of an approved warranty claim and covers outbound shipping costs.

Labor reimbursement for installation of the replacement unit is included for the first 5 years: $225 + $25 per additional inverter in years 1-2, and $125 + $25 per additional inverter in years 3-5, paid directly to the installer. You can check your current warranty status and expiration date at SolarEdge's warranty check portal (solaredge.com/us/warranty-check).

SolarEdge ONE supports several energy management modes configurable through the mySolarEdge app:

Maximize Self-Consumption: The system prioritizes using solar energy to power your home, then stores excess in the battery, then exports to the grid. Battery discharges to cover home loads when solar is insufficient, before drawing from the grid. This mode maximizes the value of self-generated energy.

Time-of-Use (TOU) Optimization: SolarEdge ONE automatically schedules battery charging and discharging based on your utility's rate schedule, storing cheap off-peak energy and discharging during expensive peak hours. Can also schedule grid charging during off-peak periods if economical.

Backup Only: The battery is held fully charged as a backup reserve and only discharges during a grid outage.

Weather Guard Mode: Automatically triggered when severe weather is forecast; charges the battery to 100% regardless of other mode settings. Returns to normal mode after the weather event passes.
