Thank you for the replies.
Confession:I hope I don't get booted from the forum but the battery
bank is for Motorhome/Land yacht. People on this board are way more knowledgable than the RV forums
which I find a little more wild west and less professional input.
The cells are Winston each single
cell @ 400AH, in which I using 8 cells in series for a nominal 24V pack.
3.0V as LV relay set point as suggested.
Zeva BMS (it has some active balancing but really only resistor shunts I think way too small to make much difference on a 400AH cell) actually the BMS I can turn balancing on and off. Does have cell monitoring display 0.005 resolution.
Dual Bus: I plan to implement a dual bus system so in the advent that charging
is disconnected loads are still connected to drain SOC, or if LV relay is tripped loads are disconnected and charging
is still possible. Exception to the rule
is the inverter/charger is going to be on the load side of the bus. I am looking at putting a secondary relay in and driving the victron inverter/charger disconnect off the HV relay, but dont plan to be plugged into shore power
AC off the inverter
are my high current
consumers, induction cooker, hot water
(it is also a heat exchanger
unit), air con (split cycle inverter
400-1200W), inverter fridge running 24/7.
DC stuff is pretty low draw stuff a couple computer fans 24/7 LED lights
, extraction fans.
Given possible memory effects?
Do I need to worry about shallow cycling, like reach full charge charging stops, current
draw runs it down soon starts charging and tops up quickly. Solar
charge controller and constant loads being the culprit.
Currently thinking of using the 10A Power supply to do initial charging until cells hold 3.35V. Then topping off any cells that need the extra juice.
