REC SI BMS
The REC SI BMS has custom profiles that integrate on the RS485 network to several well known Solar Inverters.
- Sunny Island
During the day PV powers the house and charges the battery pack. If you’re not using all the electricity that the solar PV system is generating, then the system will ensure that any surplus energy is used to charge the battery pack. Once the battery is fully charged, if there is still more solar electricity being generated, this will be exported to the grid. At time of low solar generation (night or cloudy day) the solar PV panels have a reduced or zero output, but the battery system can discharge the stored electricity, providing you with renewable-generated electricity at no additional cost. Once the battery is discharged, if you need to use more electricity, you buy it from your electricity supplier.
BMS for 24-48V systems. Note: The Q Series Standalone unit can be substituted if out of stock

Solar plants that fit the energy requirements of the everyday households are on the rise. Our goal is to make own power consumption of produced solar energy as high as possible. By using battery storage systems, you can increase the self-consumption level of “own-produced” energy for up to 40%. It makes us more independent from other energy sources (electrical grid) and it helps you save money on your electricity bill.
Estimated self-consumption level: 72,3%
