Solar Regulators

What are Solar Regulators / Solar Charge Controllers?

Solar electric power systems are essentially very simple. You have a device which converts sunlight into electrical energy (a photovoltaic panel or 'solar panel') and this is used to charge up a battery. The battery allows you to collect energy when the sun is shining and store it until needed.

This simple picture is complicated by the limitations of the battery. If you leave the photovoltaic panel connected to a battery, the battery will slowly charge up. If you are putting in more energy than you are taking out, then the battery will eventually become fully charged. If this continues, the battery will become overcharged and be damaged by corrosion of it's plates and loss of electrolyte. To avoid this, some sort of charge regulator / solar regulator is used to stop the charging when the battery is full.

Some charge controllers / solar regulators have additional features, such as a low voltage disconnect (LDV), a separate circuit which powers down the load when the batteries become overly discharged (some battery chemistries are such that over-discharge can ruin the battery).Some charge controllers may also monitor battery temperature to prevent overheating. Some charge controller systems also display data, transmit data to remote displays, and data logging to track electric flow over time.

Pulse width modulation (PWM) and maximum power point tracker (MPPT) technologies are more electronically sophisticated, adjusting charging rates depending on the battery's level, to allow charging closer to its maximum capacity.

Series Regulator vs MPPT

The MPPT versus series regulated question is not always straight forward as it very much depends on the conditions under which charging is taking place.

MPPT is good if you need to run cables from an array over a long distance as it allows higher voltage panel strings (therefore lower power loss due to cable resistance, because of lower currents).

Other than that, MPPT is useful if you don’t want to (or can’t) match the panel specifications to the battery (e.g. on a motorhome you may want to use some uncommon, high output panels since the roof space is limited).

Be aware that the % gains claimed for MPPT (other than the above couple of examples) are not likely to be ‘real world’ (e.g. How many hours during the day do your panels work at 25°C or less ?!). The hotter the panels become –the maximum power point voltage decreases and gets close to a typical battery voltage, therefore wiping out most (if not all) the gain an MPPT unit will give.

The other issues with MPPT (particularly for boats at sea) is that it’s not always easy to bypass the regulator should a fault occur (e.g. due to lightning) since the panels and battery are not matched (e.g. high voltage panels and lower voltage battery). With a series regulated system (like the Plasmatronics regulators), the system can be kept running by connecting the panels directly to the battery and manually regulating.

Mornignstar SunSaver Duo

Morningstar’s SunSaver Duo is an advanced PWM two battery controller for RV’s, caravans, boats and cottages. This product will charge two separate and isolated batteries at the same time, such as a “house” and an engine battery, based on user selectable priorities.

The SunSaver Duo employs Morningstar’s legendary SunSaver controller technology, whose long-term track record for high reliability and improved battery charging is well-recognized in the solar industry. This controller also includes a backlit remote meter which may be mounted in or on a wall, and displays digital and pictorial status information about the solar power system.
The SunSaver Duo is epoxy encapsulated for environmental protection, is user adjustable via DIP switch or connection to a personal computer, and has an optional remote temperature sensor.

Key Features and Benefits

Two Battery Charging: Solar charge current is shared between the two batteries based on a user selectable priority. When one battery is fully charged, all of the charge current flows to the other battery.

Provides Useful Information: The remote meter and LED’s display system status data and any system errors. Custom icons and back lighting make the meter easy to read and understand.

Lower Cost: Two battery charging eliminates the added cost of two separate solar charging systems and the need for isolation between the batteries.

Easy to Install: The controller is installed near the batteries using the clearly labeled large wire terminals. The remote meter may be mounted in the wall or on the wall using the included frame. Also includes the meter wiring with RJ-11 connector.

Longer Battery Life: Four stage series PWM pulse charging and temperature compensation increases the useful life of the batteries.

Extensive Electronic Protections: The controller will not be damaged by wiring mistakes during installation. There are no fuses to replace, and the controller will automatically re-set after a wiring mistake.

Highly Reliable: Epoxy encapsulation protects the controller against dust and high humidity. Efficient electronics and a conservative thermal design allow the controller to operate reliably at high temperatures. Five year warranty and estimated 15 year life.
