Well I have been looking at this for three years now.
I have recently installed three (with one to go) WTS 200AH LIFEPO4
batteries with the EV BMS and EV cell modules and with a 200A breaker on the positive line between battery
and the input side of the EV BMS HVC/LVC relay.
I have only one buss bar no separate charge and load buss bar.
I am using the EV BMS triple breaker (three times 80 A) with twin buss bars one on each side of the three relays to give me a 240 A cut off relay.
I am ONLY worrying about a LVC and I think that is highly unlikely and cant see that happening at all really. I have RC cell monitoring a bit like the Cell8 product but with a much bigger display.
I am NOT worried about an HVC in any way shape or form as I cant see how that can happen....
I have tweaked my Blue Sky 2000 solar
boost controller to cut off at 14.7 volts.
We have a TSW Xantrex 2000W inverter
WE ARE cooking
with these cells / batteries and are drawing up to 170A at times when cooking
and we hit 100A for 3 mins to boil the kettle on an induction hob.
Battery one and two (both installed together) are a bit of a mess with sense wires all over the place and I have not as yet found a good location for my cell/battery monitoring display modules.
But by battery three we have a nice professional looking installation
battery four will be another good install and then we can tidy up battery one and two's sense wiring
So far I am over the moon and very very pleased - they are performing like advertised. They are amazing LEAD IS DEAD
I need MORE solar
and another BS 2000 SB controller.
My Delco Remy internally regulated alternator
is happy, it was putting out many more amps than it is listed for AND after 45 minutes it was the same temperature as the engine
(I have a laser thermometer).
I have reprogrammed the Victron energy BMV 602 monitor
, Pukert and all other changes and it is working fine.
I set up a HV and LV audio alarms but had to lift
the HV one when we had a very sunny day and the BS 2000 SB was tripping out at 14.7 and I had set the BMV to alarm
at 14.5. The admiral was a bit upset at the noise
Typically in the morning we are 100/150AH down I need a WG to charge the batteries at night BUT today there is little wind
, sods law suggests as soon as I put on a WG the Christmas
winds will vanish (it has been blowing 20+ knots since November here in St Martin).
Pictures soon maybe :-)
