I have a multi system setup.
Power input is
1 solar array of 5 panels 1.3kw (being upgraded to 3 arrays)
Mains hookup (currently manual switchover - move plug from socket from mains to inverter output socket)
Mains battery charger
Current basic system I have
blue solar charge controller duo 12v 20a
Connected to 2 independent battery banks
Both banks are common negative and each positive banks via manual switch over switch.
These then go to busbars which high amp and permanent on 12v connections are made. This then goes to low amp 12v fused consumer board.
Off the high amp will feed my winch, 12v 40a water heater and my phoenix inverter ( not wired up yet - using cheap inverter) and my 60a 12v winch.
Also main battery bank is connected via Citrix 250a to motorhome vehicle starter battery making sure starter battery is charged while parked up. I also isolate positive on starter battery from vehicle circuit.
I have fitted but couldn’t get to work the argodiode but maybe my circuit was wrong as solar seemed to mess up system.
My system will have a mains consumer board and ats controller, lpg inverter generator and 2 extra solar arrays within the next few months.
----_------------------------
My system should finally work thus.
Keep vehicle starter battery charged from interior supply (using the Citrix??)
Have 2 common negative connected but isolated positive battery banks charged via solar, mains hook up / generator powered battery charger (victron)
I want solar to prioritise charging of starter then bank a then bank b.
While no or low solar then battery banks would be main power source with mains or generator supply used to power battery charger with secondary 240 high watt devices circuit ( for 240v water heater, oil radiator heater in winter)
Battery bank to power high amp and permanent 12v devices via victron lynx?? And phoenix inverter.
Permanent devices would be powering victron devices, 12v night/emergency led light, 12v 5g gsm router, 12v cctv cams and security ,1500w inverter connected to small chest freezer, 12v smart switches relays( switches powered but relays separate circuits)
system should be powered mainy by solar
using bank A as main supply and then switch to bank B when Bank A is low and at same time start generator to charge bank A and starter battery (via cyrix ? )
——————————————————
currently in system is 13a twin core red+black stranded 12v cable, 240v (cooker) 60a flat solid 3 core cable and 25mm red/black 170a stranded cable and 6mm stranded solar cable
Current devices
Mains socket (hookup) with extension lead for 240vac devices
12v fused consumer board
2 battery banks
Bank a= 4 x lead acid 110a/hr batteries older bank
Bank b= 3 x lead acid 140a/hr batteries newer bank
1500w inverter ( will be kept for backup when wired in following victron inverter )
Victron smart phoenix inverter 12v 3000va - 230vac
Victron -ct 12v vsr 230a - wired up
Victron Argodiode 80-2ac 2 batteries 80a
Victron blue solar pwm duo 12v 20a - wired up
Victron bluesolar mppt 150/60-mc4
Victron blue smart ip65 12v 15a battery charger 240vac
————————————
Next purchases
2 solar arrays total 9 panels
Ats avc propane 3kv inverter generator
Victron blue solar mppt 250/70-mc4?
to accommodate extra solar power in combination with Victron bluesolar mppt 150/60-mc4 to charge most depleted bank first then secondary bank
maybe using dc to dc charger???
2x Victron lynx 4 way distribution . 1 for each battery bank ?
Cerbo s gx ( to monitor and switch between battery banks and start /stop generator? Or maybe 2? For each battery bank??
2x victron smart shunts for each battery bank plus 1 for 12v fuse board ?
1x victron smartshunt ip66 for externally housed starter battery
Victron megafuses and housing with suggested placements and amp size and wire core sizes awg etc.
Ve direct smart dongle or linking cables
Isolatior/smart shunt after low powered 12v permanent circuit. Even on low battery always powered up. Even if I need make separate circuit with own solar charger and panel /s and own inverter.
reason for 2 battery banks is 1 bank is made of same battery brand and amp/hr but other bank is different brand and amp/hr abd number of batteries to oyjrt bank.
also 1 bank is older than the other.
but reason is for 2nd battery bank is A; to be backup but also B; when 1 bank is beyond use then it can be replaced without powerloss to system while waiting to be replaced/fitted and probably of different brand etc, due to low income cant afford large bank outlay
parts are purchased over time to be intergrated into system with large value items prioritised according to system min requirement over upgrade or add on
I have rough circuit diagram idea which I could send u but help would be great with parts needed and suggested circuit diagrams/ victron setup/programming and with ve direct and other control wiring circuit diagrams
Cheers in advance
