Charge controller & displays for solar panels
A charge controller is absolutely necessary for off grid solar systems for independent and self-sufficient power generation e.g. in mobile homes, caravans, campers, vans and sailboats
Function of a charge controller
The charge controller is connected to the solar modules and the battery for overcharge protection. So that the consumers do not deep-discharge the battery, the charge controller, if there is no deep-charge protection onboard, is also connected to it. The charge controller is thus the control centre and an important protection for the solar system.
Charge controller can have additional functions
Some charge controllers have a temperature sensor, an indication of the state of charge, charging current, load current, battery voltage, operating status of the solar system, warning signals and much more. SOLARA provides a charge controller with a variety of additional functions.
Charge controllers are available in different versions
Charge controllers must be matched to the battery type. Charge controllers are available in different designs and qualities. SOLARA has a wide selection for all battery types and sizes of solar systems.
SOLARA offers the right charge controller for every application – a unique selection of four renowned manufacturers

SOLARA charge controllers – Ideal for charging batteries with solar panels
The control center for all cases
We guarantee high reliability, the latest technology and ease of installation at a low cost. The regulated PWM characteristic guarantees optimum charging. All Solara controllers are so-called series regulators (no shunt) and thus very efficient. The load output protects your battery from deep discharge. A large and informative LCD shows the current system status. The SR350DUO also offers the possibility to charge two battery circuits.

MORNINGSTAR charge controller
Top technology from Morningstar with 5 years product warranty. The wide variety and the very wide performance spectrum make these controllers always the first choice.
A broad performance spectrum, innovative functions, robust design, high efficiency characterise the MorningStar solar charge controllers. ISO9001 manufacturing, quality control with 100% functional test ensure quality, reliability and longevity in the application. Over 2 million devices are installed in over 112 countries until today.
Others persist in adverse environments. We flourish in them.
With 25 years of experience and well over three million products shipped to more than 100 countries – most of them still in operation – Morningstar has earned its reputation as a world leader in the design and manufacture of solar power controllers.
At Morningstar, the word “reliability” is much more than a marketing label. It stands for a device failure rate of less than 0.4 % — the reason why we are the only manufacturer who dares to disclose such a key figure. As a result, plant designers around the world working on highly mission-critical solar power installations swear by Morningstar components, and so should you on your next project.
From mineral mines in South America to cellular signal repeaters in Canada, from natural gas wells in the Middle East to mountaintops in Nepal, Morningstar’s technology and legendary quality tip the scales when it comes to success or failure – making renewable energy a practical and durable solution that delivers value for money.
Morningstar has built its excellent reputation on faster, “smarter” signal processing, optimised thanks to outstanding engineering. In addition, as heat reduces efficiency and shortens product life, a state-of-the-art thermal design approach eliminates fan failures — unlike other higher-end solar power controller and inverter brands.
To raise the bar even higher, we use components with performance characteristics that exceed the requirements of the standards to achieve performance at unprecedented levels. The result: products that perform independently in the field and set the standards for the rest of the industry players.
Why do we develop our products with excessive precision? Quite simply, as an employee-owned company, our reputation is at stake with every Morningstar product we deliver. Not only can we afford to be perfectionists, but we also have to be perfectionists because our brand reputation is synonymous with our reputation. Thanks to our determination and ingenuity, Morningstar charge controllers maintain their legendary longevity. Meanwhile, inverter-charger combinations have reached the performance level of our controllers. In the wake of this, we at Morningstar are proud to present a solution that is also suitable for your application.
