Complete 12V Charging Kit - 100W Solar Panel + 20Amp Regulator

EcoOnlineTM is proud to offer this solar charging kit. Includes an EcoOnlineTMSolar Charging Regulator with a complete list of electronic self-protection and night timed ON/OFF function. Kit includes a connector set, a fuse kit, heavy duty insulated wire and a comprehensive EcoOnlineTM safety, information and installation manual for setting up a battery charging system.

Maximum Kit Versatility

This versatile lead-acid battery charging kit allows you to create any system configuration you want. It comes with 15 meters worth of 4.0mm² solar wiring with MC4 connectors on the solar panel and attached to the system wiring so that in the majority of installs there is no need for special MC4 connector crimping tools, simply cut the 15m system wiring with MC4 connectors attached to length. See installation manual for configuration details - EcoOnlineTM Install Manual.

For Novices - Setting up a Solar Battery Charging System

Want to start playing with solar? Please note a solar charging system must be sized right, for efficiency, reliability and safety. For your convenience we have created the following online interactive calculators to help you build the perfect set up the first time around:

  1. Solar Panel Sizing Calculator (this will help you understand the factors involved in sizing solar panels)
  2. Solar Regulator Calculator (this will help you understand the factors involved in sizing a regulator)
  3. Solar Wire Sizing Calculator (this will help you understand the factors involved in sizing wires gauges)

 Safety Requirements

  • Only use 12V “nominal” (36 cell) solar panels with this regulator. Or 72 cell panel(s) for a 24V system.
  • EcoOnline recommends solar panel wattages and connected loads should not exceed: 240W solar power (at STC for a 12V system) or 15Amp continuous load for the 20Amp regulator.
  • This regulator is to be used for charging Sealed, Gel or Flooded Lead-Acid type batteries only. Not to be used for charging any other battery chemistries.
  • Check that the maximum current produced by the chosen solar panel(s) array can never exceed the maximum allowable charging current for the battery being charged.
  • Always use appropriate gauge wires. Never exceed the rated Ampacity (amp rating) of a wire. Keep in mind that low voltage / high current wires situated in highly insulated environments cannot dissipate heat and will have a much lower Ampacity.
  • The appropriate fuse MUST be installed on the positive regulator to battery connection.
  • Do not expose this regulator to water and/or high humidity and/or corrosive environments such as those involving marine applications.
