40w 12v Photonic Universe dual battery solar charging kit (solar panel, 5m cable, 10a controller) in the is made of high efficiency monocrystalline German cells which have excellent performance characteristics and output even in low light conditions.
The is fitted with 2x5m of special and waterproof Mc4 connectors can be cut off when wiring to the or used for connecting an extension (not included).
The includes charge designed to and protect 2 x batteries or banks simultaneously.
The uses Pwm (pulse Width Modulation) technology increases acceptance and prolongs the life of your batteries.
also recover some lost capacity.
The allows setting priority e.g.
80% of power to go to the first and 20% to the second.
one of the is fully charged the will redirect all to the other battery.
The work with a single too.
If there’s only 1 connected to the controller, it will pass all to this A be added later.

A major challenge of designing off-grid PV power systems is the seasonal imbalance between the power demand of the building and power supply of the PVs. A majority of the energy produced by the PVs occurs during the summer when the sun shines brighter and for longer periods of time. The standard PV system size does not produce enough energy in the winter days to power the building and charge the batteries for nighttime. However, increasing the number of solar panels generates more energy during the winter days. I wrote an algorithm to estimate how much more solar power is required to power the building and charge the batteries for nighttime use.
