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.

From the README

Stop selling your sunshine to the grid for cents. Heat your water and charge your car with it instead. ☀️🚿🚗
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.
