Expanding an Existing Off Grid Solar Power System

Expanding an existing off grid solar power system. I install a 400 watt East facing solar array and a 150 watt West facing array to compliment my existing 640 watt South facing array to improve my battery based off grid power setup in my cabin. I install a separate Victron MPPT charge controllers for each new array. The East array is two 200 Watt Hightec panels wire in series. The West array is a single 24 volt 150 watt Solartech panel. Having multiple solar arrays facing different direction is called virtual solar tracking. It helps alleviate the workload on your batteries and allows you to run loads "directly from the panels" during daylight hours. I move my batteries into a battery box and wire up a cheap mictuning ammeter and shunt.
