It has 53 installs sharing analytics, works locally and was last updated October 18, 2026. From the [repository description](https://github.com/flashg1/SolarCharger): > Home Assistant solar charger uses surplus solar to charge your EV and home. β˜€οΈ [Open in My Home Assistant](https://my.home-assistant.io/redirect/marketplace_repository/?owner=flashg1&repository=SolarCharger&category=integration) On Home Assistant 2026.10 or older? [Open it in HACS](https://my.home-assistant.io/redirect/hacs_repository/?owner=flashg1&repository=SolarCharger&category=integration) ## Supports - **Works locally**: Talks to your devices on your own network. No vendor cloud in between. - **From the Marketplace**: Installed through the Marketplace, formerly HACS. - **Actively maintained**: Its author released or pushed a change in the last six months. ## Setting it up Install it from the Marketplace and restart Home Assistant, then add it under Settings, Devices and services. ### SolarCharger config - **Net power sensor (W)**: Sensor that expresses negative value in Watts for power exported to grid, or positive value for power imported from grid. This sensor is the feedback loop for adjusting power consumption. - **Charger current update period (default: 60 sec)**: The charger current update period must be greater than or equal to the net power sensor update period. ### After setup - **Select global defaults or device local configs** - **Supply power limit (W) (-1 = No limit)** - **Charger effective voltage (V)** - **Monday default charge limit (%)** - **Tuesday default charge limit (%)** - **Wednesday default charge limit (%)** - **Thursday default charge limit (%)** - **Friday default charge limit (%)** - **Saturday default charge limit (%)** - **Sunday default charge limit (%)** - **Reduce charge limit difference** - **Monday charge limit (%)** - **Tuesday charge limit (%)** - **Wednesday charge limit (%)** - **Thursday charge limit (%)** - **Friday charge limit (%)** Texts from the code of [flashg1/SolarCharger](https://github.com/flashg1/SolarCharger). ## Entities - **Buttons**: Reset charge limit and time - **Dates and times**: Next charge time - **Numbers**: Supply power limit, Effective voltage, Max current, Max charge speed, Power factor, Min current, Min workable current, Min workable power pause threshold, Min workable power resume threshold, Priority, Power allocation weight, Charge limit, and 27 more - **Selects**: Supply net power sensor, Weather provider, Device presence sensor, Start state, Exit condition sensor - **Sensors**: Run state, Delta allocated power, Net allocated power, Net allocated power sample size, Net allocated power data set, Median net allocated power, Median net allocated power period, SMA net allocated power, Consumed power, Consumed energy today, Instance, Share allocation, and 7 more - **Switches**: Supply cap, Charge, Fast charge mode, Poll charger update, Exit condition trigger, Schedule charge, Reduce charge limit difference, Plugin trigger, Device presence trigger, Sun trigger, Calibrate max charge speed - **Texts**: Step current list - **Times**: Monday charge end time, Tuesday charge end time, Wednesday charge end time, Thursday charge end time, Friday charge end time, Saturday charge end time, Sunday charge end time ## From the README > Stop selling your sunshine to the grid for cents. Heat your water and charge your car with it instead. β˜€οΈπŸšΏπŸš— > > EV and hot water are often the two biggest electricity users in a home, and both are perfect for soaking up surplus solar. SolarCharger watches how much power your home is exporting to or importing from the grid, and shares the surplus between them in the order you choose. For example, it can heat the hot water tank first and then send whatever's left to the car. When clouds roll in, it throttles back or pauses. When the sun returns, it picks up again. Need the car full by 7am tomorrow? It can plan for that too, topping up from the grid only as much as it has to. > > - Charge on surplus solar only. Charge current follows your "Net power" sensor up and down throughout the day. > - Charge across multiple days. Sun elevation triggers start and stop charging automatically, morning and evening. > - Smart pause and resume. Power monitor duration decides when there's too little sun. The charger is switched off while paused. > - Match your charger's steps. Configurable step current for chargers that only accept certain amp values. > - Cap your supply. Power source support - draw up to a set power offset from a home battery when solar falls short, including at night.
