About
Built in a real home in Sofia.
Solsidus started with one battery that filled to 100% every night, even before sunny days. The sun had nowhere to go.
Why we built it
A home battery is one of the most expensive things in a solar system, and most of them run on a fixed timer or no plan at all. They buy power at the wrong time, or fill up before a sunny day and leave the sun with no room.
We wanted a small box that decides every night how much cheap power to buy, only as much as tomorrow needs, and shows you why.
Measured before it was sold
Every number on this site comes from one home: our own test home in Sofia. There, night charging on a day/night tariff was worth about €54 a month. We label numbers as observed, estimated or provisional, and keep it that way.
The test home
- Inverter
- Deye 12K hybrid
- Battery
- 43.2 kWh
- Use
- 1,819 kWh a month
- Night charging was worth
- ≈ €54 a month (observed)
What we promise every owner
- It changes one setting, how the battery charges, and checks that the inverter accepted it.
- It never opens, rewires or reflashes your inverter. Its safety settings stay as they are.
- It keeps working on your home network without the internet.
- You own the box. EBB Lite needs no subscription.
