Hi all, just new to this forum that I found during my search for solutions to create my own accuwall. Hope you can help me confirm and/or guide to what I know now. Let me start by explaining what I have running atm:
- 3-phase grid power from provider with P1-mon attached to the Smart-meter
- 30x 285W solar panels and SolarEdge 8K 3-phase inverter (4 yr running, 8,5 MWh/yr)
- 8x 380W solar panels and SolarEdge 3K 3-phase inverter (installed recently)
- Main consumers: 75kW electric car and 11kW Wallbox, 1kW homelab running 7x24, average monthly consumption 800kWh (1200kWh with car charging)
My aim is to install a 3-phase battery/charge/inverter system. Inspired by 'Meine Energiewende'/Jens? I see two main options (per phase):
1. 4x Tesla 2S modules with simpBMS and Victron Multiplus II 24/5000
2. 8x LPF 280Ah batteries with Batrium Blockmon M8 modules and Victron II 24/5000 units
As far as I understand now the LPF/LifePo4 options is newer and cheaper (safer?). Not sure if/why I should go for a 24V or 48V system?!
My questions are mainly about the features of the MultiPlus charge/inverter (that will be connected to the grid/provider):
- Will the MP control the overcurrent from the solar inverters to charge the batteries automatically?
- For three-phase function, do I need to configure each MP to make them aware of each other?
- Does the MP automatically deliver battery power in case I need to charge my car?
- Do I need other (Victron) devices to complete the setup?
I'm hoping the Victron MP is smart enough to charge batteries while on solar power and deliver battery power when needed, thereby eliminating as much as need for grid-power. And, of course, deliver power when grid-power fails ;-)
Thanks in advance!
