Hello and thanks in advance for your advance.
Building a overlader on a unicel cube van on Chev 1 ton
The objective is to be able to run some power tools for this reason the choice of that size of charger inverter.
Also, no propane on board and cooking is using an induction cooktop, gasoline stove and heating with gasoline (similar to webasto diesel heater).
Also, focus on operating in low temperature, and need to explore more control and automatization to keep the battery pack over freezing temp
I like Blu boxes but if any alternative with quality components I consider it. (plan to be in remote areas so readability is prime)
Here my project:
questions:
A - how to control the charger side of the inverter when the temp is below freezing and you wan to use the inverter, with my current schematic the idea is the BMS low temperature will shut down the inverter via start relay port so is ok for not damaging in charging but you can not use the inverter
B - does make sense to have a pre-main fuse if you use a distribution center with separate fuses if the distance between batteries and the distribution center is minimal?
C - I plan to use a thermal circuit breaker to isolate the MPPT , i have already a fuse before I was thinking to use it so i can disconnect the MPP without the need of taking off a fuse does make any sense or there is no really need to disconnect the MPPT so often.
D -
E - I left out the possibility to charge the battery bank with the alternator because the cost I was calculating is to elevated to do a proper job (24 to 12 converter, thermal circuit breaker, low temp disconnect extra long wiring ) 600+ $ for extra 300W anyone agree?
F- does make sense to have a BIG disconnector just after the battery so when you park for a while you do not have any phantom loads ? or because you have your solar panel on the roof is better to leave always all connected
G- make any sense to have fuses before your 24V fusebox and before the 24-12 Orion converter?
H- to communicate with the Victron inverter you can go with a dongle and Bluetooth (but you can not change settings) or with the MK3 to USB adapter (but you need a pc to see and control the parameters) if you do not want have both what is your advice on that?
I - looks like lots of the controls from BMS to low temp to heating your battery to data log, to monitoring performance etc could be done with Arduino or Rasbery PI for cheaper, anyone has played with that?
J - I put a switch to isolate the 12 and 24 V loads, i am not sure if the same thing (without phantom loads or possible failure could be done by working on the low voltage disconnector Victron BatteryProtect 12/24V-100A.
I understand that every time you put a switch, a connection a fuse you introduce small resistance because of the nature of your connection and on low voltage that could add up, so try to prune everything is not really needed.
Lots of questions, if you have a question for me I will be happy to explain my choices if you have any advice I will be happy to listen
Thanks in advance, and thank you for our host, such a smart guy!
