Hi
I am deciding to purchase
Victron Blue Smart IP22 SLA/LiFePO4 Charger 12V 30A
Victron Blue Smart IP22 Charger 12V 30A Battery Compatibility with Renogy 50A 12V DC to DC In Vehicle Battery Charger W/ MPPT Solar Lithium
https://au.renogy.com/renogy-50a-dc-dc-on-board-battery-charger-with-mppt/
in particular when I am on shore supply connected to 240V and the Victron charger is doing its thing overnight AND then the sun starts shining in the morning what happens ?
Ideally Id like to add the Renogy ~50A of solar charge to the Victron ~30A of 240v charge. Is this possible ?
How do you set which item has precedence ? Im assuming its internal settings on one of the devices to cutout near the max voltage of the batteries an allow the other device to finish off.
How do you stop them cycling or turning each other off as thresholds are reached ?
My preference would be for the Renogy Solar to have precedence with the Victron charger being an additional source. Ideally the Victron 30A helping the solar get the Lithium batteries (2x250AH) to near full charge then cutting off to let the solar take the last bit.
The reason being when I park up overnight I can have shore supply on for 10-18 hours BUT I don't intend to connect shore supply unless I have to. Thereby meaning I wont be using the Victron charger often. As such I wouldn't want to 'decrease' any of the Renogy Solar charger characteristics as the Solar and Alternator Driving are my main source of charge for 99% of occasions.
I also don't want to have to 'just switch XYZ or just turn off XYZ' when you connect shore supply as human intervention is the worst type of system (that's code for i will forget to do XYZ ! :) )
Is it possible to program custom modes into this Victron Charger:
mode 1 - I am parked up for 18 hours overnight undercover with no solar - 100% Charger
mode 2 - I am in sorta bad weather parked outside - split charger/solar
Any explanations welcomed !
