Hello, I'm seeking assistance in designing a Victron backup power system with minimal expenses. Due to ongoing blackouts in Ukraine, I need a reliable reserve system. Despite extensive research on Victron products, I still have several questions.
Here is my possible design, I would like you to edit/review it:
Proposed System Components:
- Victron Energy MultiPlus-II 48/5000/70-50
- Lead-Acid Traction Batteries (currently 10.6 kWh, plan to upgrade to lithium in the future)
- BMS for lead-acid batteries (to be determined)
- Lynx Distributor or Power In
- Cerbo GX
Questions and Concerns:
- Battery Monitoring: Can the MultiPlus-II inverter monitor discharge/charge thresholds of 48V lead-acid batteries connected in series?
- BMS Requirements:
- Is a BMS necessary for lead-acid batteries?
- If yes, which BMS would you recommend?
- Can the MultiPlus-II communicate directly with the BMS to determine charge/discharge thresholds?
- Where should these thresholds be set: inverter, BMS, or both?
- Lynx Shunt VE.Can: What is its purpose? Does it replace the BMS?
- Configuration for Lead-Acid Batteries:
- How to configure the MultiPlus-II for lead-acid (traction) batteries?
- Should configuration be done via Bluetooth or VEConfigure program?
- Can i temporarily operate without Gerbo GX, and add it in the future?
