What do I need a solar regulator for?
Solar regulators 12V control the solar systems for motorhomes, caravans, caravans, camping buses, summer houses and boats. This means that the 12V charge controller controls the flow of current to the solar battery. This control of the solar regulator normally prevents overcharging or deep discharging of the solar battery. Good solar controllers can be adjusted to the type of battery to be charged. This optimised charging characteristic allows the 12V charge controller to fully charge the solar battery faster and prolongs the life of your battery. These good solar controllers take into account the exact state of charge of your battery. This is determined by various factors:

  •     Discharge time
  •     Discharge current
  •     Temperature
  •     Ageing condition


There are a total of 3 different types of 12V solar controllers. At Reimo, we offer you the PWM solar controller and the high-quality MPPT charge controllers. The cheap series charge controller, which is also still on the market, has not proven itself for motorhomes, caravans, camping buses, summer houses and boats. The advanced 12V charge controllers such as the MPPT charge controller cost a little more, but are easier on your solar battery.

Votronic Solar Controller, NDS 12V Solar Controller Carbest 12V Solar Controller or MPPT Controller?
Carbest 12V charge controller, Votrionic solar controller or NDS 12V solar controller, here we have put together a selection of the most popular solar controllers for motorhomes, caravans and camping buses. Whether very cheap, innovative or Made in Germany, there should be the right solar controller for everyone here!
Carbest charge controller, Reimo's own production. For many years we have had solar controllers manufactured according to our quality specifications. Included in the scope of delivery of the Carbest solar sets, the Carbest solar controllers are successfully installed in large quantities. This is also reflected in an extended warranty of 3 years. Carbest solar controllers are available in a wide range from simple PWM charge controllers to high-quality MPPT controllers. Due to the frequent installation of Carbest solar controllers, continuous improvements can be incorporated into the production flow.
Votronic solar controllers belong in a family with the well-known battery monitoring devices, tank level indicators, battery computers and many indicator panels. Votronic display panels can be found in many motorhomes.
Reimo has been selling NDS 12V solar controllers for several years. NDS is a specialist for batteries and charging technology for motorhomes, caravans and buses. The reasonable price-performance ratio of the NDS 12V solar controllers is well worth a second look!

The MPPT charge controller, charging at the limit with the MPPT solar controller
MPPT charge controllers optimise the charging currents. The current generated by the solar modules is subject to constant change. Various factors are responsible for this, here are a few examples.

  •     the temperature of the solar module (optimal at approx. 21 degrees)
  •     the time of day
  •     the incidence of shade, e.g. partial shade under a tree
  •     the module type

An integrated controller in the MPPT charge controller monitors these changing conditions and controls the charging so that the greatest possible charging success is always achieved. MPPT charge controllers thus ensure an average of 20% more electricity yield. This is achieved by the solar controller constantly searching for the optimum voltage point with the highest solar output of the connected panel. With such a high degree of efficiency, an MPPT charge controller can continuously produce electricity (albeit on a smaller scale) even under difficult conditions such as clouds, cold or heat. An MPPT charge controller "maintains" your solar battery. Whether acid, gel, AGM or lithium 12V battery, an MPPT charge controller supplies the different battery types with optimal power and maintains the performance of your solar battery for a long time through this intelligent battery care.

PWM charge controller with shunt technology
PWM charge controllers prevent overcharging of your solar battery by "short-circuiting" the panel. The 12V solar controllers with PWM (pulse width modulation) generate analogue signals via a digital signal source. With the PWM solar controller, only two components are taken into account, the duty cycle and the frequency. This results in a voltage level with only 2 different settings. Simply put, the PWM solar regulator is a switch. When the switch of the solar regulator is on, the solar panel is used to charge the solar battery. When the constant voltage of the solar battery is reached, the PWM solar regulator is switched off by the short circuit mentioned. The state of charge of the solar battery is maintained by constantly switching the solar regulator on and off. PWM solar controllers are perfectly okay for installation with long, constant charging times, such as when installing the solar system on the roof of your garden shed. The MPPT solar controller is the better choice for changing conditions and approx. 20% more current speaks for itself.
