Home Battery
A home battery stores solar or off-peak energy and reports state of charge and power flow to Home Assistant. Local integration lets automations manage backup reserves, time-of-use arbitrage, and outage response.
A home battery banks energy from the sun or the grid and hands it back when it is worth more: during peak rates or an outage. Integrated locally, Home Assistant sees state of charge, charge and discharge power, and grid status in real time, so the battery becomes something automations can plan around rather than a sealed box.
How Selora AI uses home batteries
- State-of-charge tracking in the energy dashboard, with alerts when reserves run low ahead of a storm.
- Time-of-use recipes that hold charge for peak windows and top up when rates or solar make it cheap.
- Outage response that sheds non-essential loads the moment the home switches to backup power.
Why home batteries matter
Storage is what turns solar from a daytime discount into an energy strategy. When Home Assistant can read the battery locally, the whole home can coordinate around it, and monitoring keeps working through the exact grid outages the battery was bought for.
Compatible devices
IQ Battery 5P
AC-coupled LFP home battery with 5.0 kWh usable capacity and 3.84 kW continuous output (7.68 kW peak) from six embedded grid-forming microinverters. Modular design stacks to 16 units for 80 kWh, backed by a 15-year limited warranty.
Home Battery 400V
DC-coupled LFP home battery storing 9.7 kWh per unit, stackable up to three per inverter for 29 kWh. One of the first residential batteries to pass UL9540A unit-level fire testing, permitting indoor installation, and DC-coupling keeps round-trip losses low by skipping a conversion step.
Powerwall 3
Integrated home battery and solar inverter: 13.5 kWh usable LFP storage, 11.5 kW continuous output, and up to 20 kW of DC solar input across 6 MPPTs in one unit. Starts heavy loads up to 185 LRA, so a single unit can back up most homes including HVAC.
