The maximum limits as until now documented in datasheet and manual have been, on purpose, conservative. After having more experience, and more time spent on testing in R&D, we are confident to be able to increase the maximum system sizes.
The rule was max. 5 batteries, or max. 5 battery strings, in parallel.
Per now the new rule is a maximum of 20 batteries in total. Ie. no more limit on how many parallel batteries/battery-strings that results in. This allows for significantly larger 12 & 24V systems. And for 48V it allows for a slightly larger max system and built in a better way: using 24/200Ah batteries, instead of many 12/330Ah. Which is better: a string of 2 x 24V battery needs less balancing than a string of 4 x 12V batteries.
This change and these limits apply to all BMS-es, ie Lynx Smart BMS, BMS 12/200, BMS 12/100 CL, the VE.Bus BMS and the smallBMS.
- 12V bank maximum: 20 x 12V/330Ah = 84kWh
- 24V bank maximum: 20 x 24V/200Ah = 102kWh
- 48V bank maximum: 20 x 24V/200Ah = 102kWh
There are no related hardware modifications or firmware updates. This change applies to all existing and new stock.
