The sun, after dark.

Solsidus keeps the day’s sun for the night and buys the rest when electricity is cheap. It plans your home battery around tomorrow’s sun, your local prices and what your home needs. One small box, in your home.

A solar home at dusk. The sun sets, the sky fills with stars and the house stays lit from its battery. Tonight’s plan reads: charge to 74 percent.

Pay less

The battery fills in lower-cost periods, so you buy less when electricity is expensive.

Keep room for the sun

It leaves space for tomorrow’s sun instead of filling up early.

Stay in control

One bounded setting changes when the plan calls for it. You can see it, and nothing else is touched.

Spend less

Buy the rest when it is cheap.

Solsidus uses a supported live market feed or your supplier’s price schedule, together with tomorrow’s weather and your own usage. No guessing or manual rescheduling.

Protect the battery

Full only when it helps.

A battery kept at 100% after every charge ages faster. Solsidus charges to what the next day needs.

Quiet, local control

One safe target. Nothing critical.

The box applies the target for the next useful charging window and checks that the inverter accepted it. Safety settings are never touched.
