SunSaver is a fully epoxy encapsulated outdoor rated 10 Amp charge controller

If you're looking for a reliable charge controller that's rated at 4.5A for outdoor use, the SunSaver is the ideal solution. This outdoor rated, fully epoxy encapsulated 10A controller is available in six and twelve amp capacities. It offers temperature compensation, built-in lightning protection, and easy 4-wire hookup. The controller has a default regulation voltage of 14.1V, which is ideal for gel and sealed batteries, and the SunSaver is fully outdoor rated for up to 70 degrees. The SunSaver is small enough to fit on a single module and is highly durable - its dimensions are just 2.5" x 2.0" x 1.5" and it weighs less than three ounces.

SunSaver is qualified for oil and gas installations. It also features bi-color charging status LEDs. The third LED indicates battery voltage state. Unlike conventional chargers, SunSaver is fully epoxy encapsulated. SunSaver charge controllers have a five-year warranty. It is rated for outdoor use and is compatible with 12 and 24V systems.

The SunSaver is a highly efficient solar charge controller that is surprisingly affordable. It features advanced PWM pulse charging algorithms, selectable battery type, temperature compensation, and Load Low Voltage Disconnect. Unlike traditional chargers, the Load Low Voltage Disconnect prevents battery discharge when the voltage reaches two-thirds of the maximum. Morningstar recommends that you charge the battery with no more than two-thirds of the maximum voltage.

The Morningstar SunSaver is the world's best small solar charge controller. It includes standard features not found in other small PV controllers. It provides exceptional performance and value with Morningstar's innovative manufacturing approach. It offers flat-rate shipping to the lower 48 states. The SunSaver is also rated for use with flooded and sealed batteries. It is highly customizable to meet your needs.

The MorningStar SunLight Controller combines the SunSaver with a built-in LVD. This controller automatically activates lights after dark, a timer for two to eight hours, and a test button to determine if the lighting is working properly. It is available for both 12V and 24V systems, and is rated at 10 or 20 amps.

It uses an advanced series PWM charge control for constant voltage battery charging

The SunSaver MPPT solar charge controller uses an advanced tracking algorithm that prevents over-discharge. It is well-suited for both professional and consumer PV applications, and its charging process has been optimized for long battery life. This charge controller is compatible with either flooded or sealed batteries, and features a rugged aluminum case, epoxy-encapsulated electronics, and LED charging and load control indicators in LVD models. The company also offers a five-year warranty.

The SunSaver Duo controller has a backlit remote meter that can be mounted in or on the wall. It displays pictorial or digital status information in both English and Spanish. Its electronic circuitry is epoxy-encapsulated for environmental protection, and user-adjustable via DIP switches. It can also be connected to a personal computer, and includes an optional remote temperature sensor.

The SunSaver RECC series offers a number of advanced features. High end models offer integrated temperature compensation, PWM regulation, LCD display for battery status and energy flows, and a built-in nightlight function. It has three modes of deep discharge protection: SOC controlled, voltage controlled, and adaptive (fuzzy logic) modes. PWM pulse charging also has advanced capacity recovery capabilities and enhanced charge acceptance.

SunSaver RECC's PWM charge control for constant voltage battery charging is superior to MPPT. MPPT is a better choice for small and large solar panels, and the SunSaver RECC uses an advanced series PWM charge control for constant voltage battery charging. The PWM charge controllers use the same PWM technology as most high-quality solar chargers.

For maximum performance, SunSaver RECC is best used in combination with the SunLight. In parallel configuration, both SOLAR and SunLight may be connected. The SunSaver RECC has a higher capacity and can handle more amps. SunSaver RECC is only compatible with a 12-volt system battery. If the battery does not meet the minimum voltage requirements, it will display a red LED instead.

Maximum power point tracking (MPPT) solar charge controllers utilize advanced algorithms to control voltage and current. This technique allows the PV array to operate at its maximum potential voltage. Depending on the panel and battery voltage, MPPT solar charge controllers can improve their efficiency by 30% or more. The SunSaver Renewable Energy Controllers MPPT solar charge controllers are also much more reliable than PWM charge controllers.

It prevents the battery from discharging through the PV array at night

High-end SunSaver Renewable Energy Controllers include built-in temperature compensation, PWM regulation, and integrated temperature sensors. The LCD display shows panel voltage and energy flows, as well as battery voltage. Deep discharge protection features include voltage and SOC controlled modes, adaptive (fuzzy logic), and low voltage disconnect. A programmable nightlight feature is also included. It has all the features you'll need to prevent the battery from being overcharged or discharged.

The SunSaver's intelligent circuitry minimizes switching noise and filters all output noise to very low levels. It is designed to prevent reverse current leakage at night by regulating the power from the PV array. The SunSaver does not require a blocking diode. The controller's multi-color LED indicates battery charge levels, and three battery state-of-charge LEDs tell you the controller's current status.

When installing your solar array, make sure you buy the right size for your area. Large solar panels can exceed the charge controller's maximum capacity and cause smoke. The last thing you want is a smoke-filled charge controller. That's why a charge controller with built-in temperature sensor is essential. A better controller will also have a remote temperature probe that reports battery temperature to the controller. However, if you're unsure about battery size, you can always manually compensate for temperature. Manual compensation may be sufficient once or twice a year, but should be checked for accuracy.

Another important function of the SunSaver Renewable Energy Controller is to block the reverse flow of current. This prevents unnecessary discharging and increases battery uptime. Solar panels pump current through the battery in one direction, but during the night, they may pass current in reverse direction. An under-voltage battery is when the battery loses 80% of its charge. If you do not want this to happen, the SunSaver Renewable Energy Controllers prevent the battery from charging through the PV array at night.

The controller's preferred charge set points vary according to the temperature of the battery. It may not be able to reach the float stage before the next cycle, resulting in excessive overcharging. If the temperature rises above this level, the charge controller may not be able to keep up. In addition to protecting the battery from overcharging, the controller may also prevent overcharging.

It has a bi-color charging status LED

In addition to a battery-level charge-state LED, SunSaver Renewable Energy Controllers have specialized oil-and-gas qualification. The charging status LEDs indicate the voltage of the battery and the controller's charging status. The charging status LED is bi-color so it will indicate the battery's level of charge. A third red LED indicates the battery is fully charged.

The SunSaver MPPT solar controller utilizes TrakStar Technology for optimal battery charging and reduces wasted energy. It features a four-stage charging algorithm that uses 100% of the solar energy to recharge the battery. Additionally, the SunSaver MPPT is equipped with a temperature sensor to prevent battery over-discharge. For added convenience, it also features self-diagnostics and terminals for remote battery temperature measurement.

The Morningstar SunSaver Gen3 solar charge controller is the world's most advanced PWM solar battery charging and load controller. It is made for both consumer and professional applications and has several unique features. Its marine-rated terminals and epoxy-encapsulated electronics provide extreme durability and protection. It is also the preferred choice for oil and gas applications. This controller includes a bi-color LED that indicates the battery's charging status.
