Hi people,
Hoping I can get confirmation that I'm on the right track here. I'm no expert but I've made a couple of wiring diagrams, one mainly showing the DC circuitry and the other expanding out the AC circuits from/to the inverter.
I'm planning on putting all the AC gear into a small consumer unit.
I plan to get the AC in power to the inverter from an existing power socket in the utility room and use the earth cable from it as the earth for the system. If the grid goes down I assume I might need another earth, so could install an earthing rod to connect to in this rare case. I'm based in the UK if it matters.
The equipment I already have is -
Victron Multiplus II 48-3000-35-32-GX
45A Victron MPPT Smart Solar 150-45 - 150VOC Solar charge controller 12 , 24 , 48V
3 x 375W Canadian Solar Mono Half Cell Panels - Super High Power Mono PERC HiKU (only using 3 in this config until I move house soon when I'll expand out with another 7 panels, another inverter and another MPPT)
2 x Pylon 3.5kWh US3000C Li-ion Battery - 48V Lithium
2 x STÄUBLI MC4 Solar Connectors - Pair (Male & Female) suitable for 4mm and 6mm cable only
2 x 20A DC DIN Mount Breaker 125V MCB C curve
Outback DIN Mount Breaker 60A 150VDC
Victron Mega fuse 125A for 48v systems
Victron Mega fuse holder, Stand alone with cover
350A Battery Isolator Switch - Blue Sea E Series 48V
2 x DIN mount rail 35mm 10cm long for DC or AC Breakers
2m x 16mm cable - Large Charge Controller or Inverter to Batteries
100m x 6mm Solar Cable
Victron VE Can to CAN-bus BMS Cable 5 metre Type A
Pylon Batteries DC Cable Pack 25mm
Victron VE Direct Cable 1.8m, straight both ends
Pylon battery Wall Mounting Cabinet PRO
If the AC diagram is ok I'll need to also buy -
2 x 16A RCBO's
1 x 32A RCD
1 x MCD (16A?)
Consumer unit
Ground rod (backup earth)
Also will need several metres of red and black 35mm2 cable to connect the inverter and MPPT to the battery under the counter.
Sorry if I've been a bit long winded here, just like to get all the details down. What do you think, have I got it half right? Any suggestions or comments would be much appreciated.
Oh, I've mounted most of the equipment, before realising I might have to move it a bit to make space for the AC consumer unit, unless I put that on a separate board.
Thanks vey much!
