Choosing the right solar charge controller regulator.
Very low profile solar panel and regulator.
Full laser patterning a patented process using a computer controlled laser interconnects all solar cells.
This is why we need a regulator or solar charger.
A fully charged 12 volt battery is around 12 7 volts at rest around 13 6 to 14 4 under charge so the panel has to put out at least that much under worst case conditions.
A 100w solar panel divided by 12 volts equates to 8 3 amps.
A solar charge controller also known as charge regulator or solar battery maintainer is a device that manages the charging and discharging of the solar battery bank in a solar panel system.
A solar charge controller frequently called regulator is similar to a regular battery charger i e.
Most common 24v 60 cell solar panels have a vmp of 30v to 34v.
Why do you need a solar charge controller.
This controller and its charging al.
The panels need to provide some extra voltage so that when the sun is low in the sky or you have heavy haze cloud cover or high temperatures you still get some output from the panel.
In the case of 24v batteries there is no problem when 2 or more solar panels are connected in series but there is a problem when only 1 solar panel is connected.
Which have the ability to discharge to very low levels without sustaining long term damage.
Hrsi 12v solar panel regulator.
Further this circuit is capable of operating panels at very low power levels.
Trina solar is one of the worlds largest solar panel manufacturers and are investing heavily in new generation of low cost high efficiency panels.
Deposited onto a solar grade glass superstrate.
The well known trina honey range of panels from trina solar are considered great quality and very good value for money in particular the honey m monocrystalline range of panels which are now available in the more efficient half cut 120 cell.
The itechworld 30 amp mppt solar charge controller is designed to enhance any solar and battery combination it works especially well with the itech120 lithium battery and itechworld solar panels.
This module comes complete with a low profile impact reinforced lexan frame which protects the back and edges of the panel and 1 2m of 2 core 18awg flying leads.
At very low power levels it is difficult to measure a peak in the imon output as the panel scan is run.
See all solar charge controllers.
Also 24v solar panels are not a problem as they operate in the 30v to 40v range.
It regulates the current flowing from the solar panel into the battery bank to avoid overcharging the batteries.
In this case it is often most beneficial to employ an mppt algorithm that reads both the panel voltage and the imon output during an mppt scan.
However an unregulated 12v solar panel can output up to 22 volts in full sun.
The hrsi regulator is a micro controlled voltage regulator that provides multi stage charging levels as well as over voltage protection the bulk and float phase charging levels coupled with temperature compensation ensure that battery condition is more effectively maintained thus improving battery capacity and life.
