If you discharge a Battery to deep it will receive permanent damage, therefore a load controller disconnects the battery before this happens.
"System Management for renewable and sustainable energy"
What it all boils down to..
All systems have some form of control:
Even our most basic system will deploy some form of management, it usually revolves around Load Control, Charge Control, Conversion Control and Annalists / Information.
These units have many functions and possibilities and often more than one type of unit is deployed to achieve the desired result.

Battery Control
This is usually part of the Charge controller which simply disconnects your batteries once they are depleted. In larger systems Inverters are able to start Generators. There are also relay units available which are preprogrammed to turn of loads ( up to four ) in order of importance. This means that some of the load will be shed to preserve the batteries longer without leaving you in the dark.

Power Guard 220V - AC
Usually used as a stand alone, the unit integrates into your Distribution Box where Power is managed when the unit automatically switches off appliances as soon as an excessive load is sensed, such as during peak demands. The unit limits the amperes (current) flowing through the electricity system. Selected appliances remain switched off for a period of time, typically 20 minutes. In about 20 minutes the intelligent unit assesses the power load again and then may switch the units back on, or keep it switched off for longer. A great feature is that consumers can decide which unit has the lowest priority for them and that unit will be switched off first. The unit can be programmed to switch off appliances in order of priority from low to high.
"Charge Control"
A must for Batteries
The most basic and essential component , this unit ensures that your batteries are keep in prime condition.
"Load Control "
Control your Load without damaging your batteries
"Diversion Control"
Don't waste energy - divert it
In alternative energy systems one often has more energy available then the batteries are able to absorb, therefore it is possible to divert this excess energy to a resistive load.
"Intelligent Switching"
Switch it - the clever way
Intelligent switches come in many forms some examples are, time based, trigger time based, access based. There is a solution available which will save energy by simply switching sources on and off automatically.
"Sensor Control"
Sense, when you need it
Sensor switches are deployed when a measurable action requires a reaction. Light sensitive switches, pressure switches, water switches, temperature switches and passive infrared sensors are all examples of sensor based switches. It is possible to combine various switches together to arrive at the following example: A light sensor will sense night time and trigger a motion sensor which will trigger a light for a set period. In this example we have a night light that only triggers with motion and stays on for a set period of time, perfect you will never forget to switch a light of in your garage or outdoors.
