Hi guys,
My van currently has (4) 160W 12V panels separated into 2 different arrays (each going to its own charge controller - i have 2). For space reasons, i will be ditching (2) panels and replacing with (1) Panasonic 330W panel. So the (2) remaining 160W 12V panels will be wired in series in their own array on one charger. The (1) Panasonic 330W panel will be on its own, utilizing a EPEVER 40A MPPT charge controller. My battery bank is 12V composed of (2) 200Ah LifePO4 batteries.
Does charging my bank with two separate arrays of different voltage pose a risk? Anything I need to change first? I'm not sure about this Panasonic panel..it's not actually listed as a 12V or 24V. The 40A MPPT appears to be appropriately rated. The Panasonic 330W panels specs are as follows:
EPEVER 40A MPPT
40amps solar charge controller, Max input power 520W(12V); 1040W(24V) solar panner, Max. solar array Voc 100 V;
Thank you for any help
