After seeing the performance of the new MPPT solar system on our 100-year-old barn.
I now have big plans for next summer, to completely remove and replace our current power system (relocating it to my shop building)
Until then, for this winter, I have made a slight improvement.
I have four solar panels on the roof, two of which are matching 150-watt panels.
I separated the wiring at the panels. Combining the two 150-watt panels in series to a Victron MPPT smart solar charge controller and directly to the batteries.
I still need to order and install an inline fuse, but for now, we are up and charging!
The other panels will remain wired in parallel as they have been for many years.
During a mid-afternoon thunderstorm today, I was still receiving a charge from the Mppt control!
Next summer, I will switch to 48-volt LiPo batteries with an all-new solar system for the house.
