Why Go Solar?

Applications

Sheds, Stables, Boats, Caravans, Motorhomes, electric fencing, road/ path/ driveway illuminated signage, campsites, yurts, multi-panel off grid power source for small buildings, remote telecoms, mobile food outlets, and many more…

Independent Off-Grid Solar Power Source

One or more solar panels can be connected a battery bank and power inverter using a solar charge controller. You can therefore have a 240v power supply anywhere in the world without grid supply. Please see our solar power kits.

Solar Panels do still generate power during cloudy and rainy weather!

We have a rough guide below to solar panel power output relative to weather conditions:-

100% power output – clear sky midday sun with the panel fully tilted toward the sun’s position in the sky.

75-85% output – clear sky midday sun but with the panel laid flat

50-65% output – thin cloud, or intermittent small clouds

10-20% output – midday overcast sky or rainy conditions

Technical Specifications

20w Poly-Crystalline Solar Panel with 1 metre cable

  • Maximum Power (Pmax): 20W
  • Maximum Power Voltage (VMP): 18V
  • Maximum Power Current (IMP): 1.12A
  • Open Circuit Voltage (VOC): 22.54V
  • Short Circuit Current (ISC): 1.19A
  • Weight: 1.8KG
  • Size: 480 x 350 x 23mm
  • Power Tolerance: +/-3%
  • Maximum System Voltage: DC1000V

In the event that the solar panel is in shade for a prolonged period, our solar panels either have one or two built-in bypass diodes which will enable the panel to continue generating.

Solar Panel Battery Charge Regulator Controller 12V / 24V Auto Switching

Solar charge controllers are required to regulate the power output from the solar panels to ensure effective charge of a typical 12V or 24V lead acid battery without overload.  PWM (Pulse Wave Modulation) solar charge controller provide a cost-effective solar charger for the solar panel outputs in our range. Optimised charge control which helps to prolong the life of the battery. 3-6% more effective than non-PWM charge controllers.  LED indicator light to show battery state.  Uses industrial grade micro-controller chip to work in a wide range of temperatures and humidity.

Warning: The Connection Order Below must be followed

1, Battery Cable, 2 Load Cable, 3, Solar Panel Cable

Do not install the charge controller in a sealed enclosure where battery gases can accumulate.

These charge controllers can be used with one or more 12V batteries where additional storage capacity may be needed.

Solar Panel Battery Charge Regulator Controller 12V / 24V Auto Switching

Solar charge controllers are required to regulate the power output from the solar panels to ensure effective charge of a typical 12V or 24V lead acid battery without overcharging.  Charge controllers also help to prevent reverse power discharge from the battery back into the solar panel at night as they act in the same way as a blocking diode.  PWM (Pulse Wave Modulation) solar charge controllers provide a cost-effective solution to linking your solar panel to the battery.  Optimised charge control helps to prolong the life of the battery. The LCD display shows gives an indication of battery charging state and battery voltage.  The display also indicates solar power input or power discharge from the battery.  Our charge controllers use an industrial grade micro-controller chip to work in a wide range of temperatures and humidity.

Solar Charge Controller – Technical

  • 10A max Rated Discharge Current and Rated Charge Current.
  • Suitable for 12V or 24V systems, auto detecting & auto switching
  • Only suitable for lead acid batteries: Sealed wet lead acid, AGM, GEL.  This controller is not suitable for nickel metal hydride, lithium ion or other batteries.
  • Maximum solar input; <50V
  • Equalisation; Sealed 14.4V, Gel 14.2V
  • Float Charge; 13.7V (by default, value adjustable)
  • Load outlet discharge stop – 10.7V (by default, value adjustable)
  • * Discharge Reconnect – 12.6V (by default, value adjustable)
  • USB outlet – 5V/3A maximum.
  • Self-consumption <10mA (0.12w at 12v)
  • working temperature range -35 to +60 Deg C
  • Dimensions – 150 x 78 x 35 mm
  • Weight – 150 grams

* Discharge reconnect meaning.  This voltage is user adjustable.  As the load consumes the power within the battery, the voltage eventually drops to 10.7V and the load output of the controller will automatically stop any further charge from protect the battery.  If for example the next day maybe rainy or cloudy day and the battery charges slowly, if the voltage is still below 12.6V, the load output from the controller will still not work.  If the sun comes out in the afternoon, or the next day is much sunnier conditions, once the battery voltage rises above 12.6V, the controller load output will automatically start to work again.  Discharge reconnect is set to 12.6V by default, although you may wish to set this perhaps 12.4V.  Discharge reconnect is aimed at protecting the battery and reducing the depth of discharge cycling.  Lead acid batteries last longer with shallow discharge.

Installation

1, make sure your battery has enough voltage for the controller to recognise the battery type before first installation.

2 the battery cable should be as short as possible to minimise loss.

3, this charge controller is only suitable for regulating solar panels.  Never connect another charging source to this charge regulator.
