Solis Stackable High Voltage BMS
Solis Stackable High Voltage BMS
Solis Stackable High Voltage BMS
Solis FlexHome stackable BMS — Sold on its own — and the minimum module count is not the same on HV and LV.
SolisStorage FlexHome is a stackable battery: modules in 5 kWh increments, built up to the capacity a household needs, with the management unit at the base of the stack.
About the Solis FlexHome stackable BMS
The BMS is what makes the stack a battery. It balances the modules, talks to the inverter and enforces the limits, and on its own it stores nothing — the modules are always a separate order.
The minimum system is the part that catches people out, because it is not the same on the two lines. A high-voltage BMS needs three HV modules to make a working system. A low-voltage BMS needs one LV module.
Both lines use LiFePO4 cells, support 90 % or more depth of discharge, and are rated for over 6,000 cycles — around ten years of service. Each pack functions as a standalone unit and up to four run in parallel.
What does this fit?
This is the management unit a stackable FlexHome battery is built on.
The BMS is sold on its own and does nothing without battery modules. The minimum system differs by voltage: one high-voltage BMS needs three HV modules, while one low-voltage BMS needs a single LV module.
The products it is ordered with:
What the job needs
The details that decide whether this suits the system:
- The BMS does not include battery modules.
- High voltage: one BMS plus a minimum of three FlexHome HV modules (SOL-SBAT-R5K-H-ST-OD) makes a complete system.
- Low voltage: one BMS plus one FlexHome LV module (SOL-SBAT-R5K-L-ST-OD) makes a complete system.
- FlexHome HV covers 15 to 40 kWh and FlexHome LV covers 5 to 40 kWh, both expandable in 5 kWh increments.
- Each pack works as a standalone unit and up to four run in parallel.
- LiFePO4, 90 % or more depth of discharge, over 6,000 cycles.
Where this earns its place
The BMS is chosen by the battery line it manages.
Things worth knowing about this listing
- A Solis FlexHome HV battery module (SOL-SBAT-R5K-H-ST-OD) is required separately. For a complete system, 1 BMS plus 3 battery modules are needed.
Solis High voltage BMS technical data
Questions we get asked about this inverter
Does the BMS come with batteries?
No. Battery modules are always a separate order.
What is the minimum system?
On high voltage, one BMS and three HV modules. On low voltage, one BMS and one LV module.
How far does it expand?
FlexHome HV runs 15 to 40 kWh and FlexHome LV runs 5 to 40 kWh, both in 5 kWh increments, with up to four units in parallel.
What chemistry and life?
LiFePO4, 90 % or more depth of discharge, over 6,000 cycles — about ten years.
