Regulators are a critical part of any solar-powered battery system. The regulator controls the
amount of charge being led into the battery and protects the battery from overcharging.
How to choose the right regulator -- three main pointers
- The regulator must match the voltage of the battery.
- The regulator must match the battery type, e.g. sealed or flooded
- The regulator must match be sized to handle the maximum current that the array is capable of producing, with a
reserve for future system expansion or extreme weather days when the panels exceed their rated performance levels.
We offer two types of regulators.
1. Series Switching Regulators.
These are simple regulators that monitor the battery voltage and disconnect that panel when the battery is charged.
They are compact, reliable and economical
2. Pulse Width Modulation Regulators.
These are microprocessor-controlled regulation that deliver power to batteries in multiple stages. In most cases they
are adjustable and usually include extra feature such as volt & amp meter. light control, data-logging or auxiliary
load circuits.
Maximum Power Point Tracking Regulators
MPPT regulators are ideal for water pumping systems or locations where the solar array
is a long distance from the batteries. These regulations allow the array to be wired
at a higher voltage than the batteries, taking advantage of lower transmission losses
and smaller cable sizes. The regulator will also track the maximum operating point
of the array, leading to an increase in available power of up to 30%!
