Multi Contact Cables MC4 Australia (Solar Enertech)

Most solar panel manufacturers are moving towards usage of sealed junction boxes with a weatherproof cable connector system. The Multi Contact design replaces the common open access screw terminal junction boxes that can sometimes experience problems with corrosion. To connect a single panel or single string of panels fitted with Multi Contact cables to a solar regulator, a male to female Multi Contact extension cable can be used. The single core cable is cut in half giving two cables - one with a male plug and a bared wire end and one with a female plug and a bared wired end. The plugs mate up with the connectors at the back of the panel and the bared wire ends can be inserted into the screw clamp terminals in the solar regulator. Available in lengths of 2m, 5m, 8m and 12m (after cutting the effective length will be halved).
2 Meter Cable: $20.00
5 Meter Cable: $25.00
8 Meter Cable: $29.00
12 Meter Cable: $37.00

Common types of alternative energy

Solar energy

Solar energy is generating of electricity from the sun. It is split up into two types, thermal and electric energy. These two subgroups mean that they heat up homes (and water) and generate electricity respectively.

Wind energy

Wind energy is generating of electricity from the wind.

Geothermal energy

Geothermal energy is using hot water or steam from the Earth’s interior for heating buildings or electricity generation.

Biofuel and ethanol

Biofuel and ethanol are plant-derived substitutes of gasoline for powering vehicles.

Hydrogen

Hydrogen is used as clean fuel for airplanes, spaceships, and vehicles.

Charger Controller Types

Charge controls come in 3 general types (with some overlap):

Simple 1 or 2 stage controls which rely on relays or shunt transistors to control the voltage in one or two steps. These essentially just short or disconnect the solar panel when a certain voltage is reached. For all practical purposes these are dinosaurs, but you still see a few on old systems. Their only real claim to fame is their reliability - they have so few components, there is not much to break.

3-stage and/or PWM such Morningstar, Xantrex, Blue Sky, Steca, and many others. These are pretty much the industry standard now, but you will occasionally still see some of the older shunt/relay types around, such as in the very cheap systems offered by discounters and mass marketers.

Maximum power point tracking (MPPT), such as those made by Xantrex, Outback Power, Morningstar and others. These are the ultimate in controllers, with prices to match - but with efficiencies in the 94% to 98% range, they can save considerable money on larger systems since they provide 15 to 30% more power to the battery. For more information, see our article on MPPT.

Most controllers come with some kind of indicator, either a simple LED, a series of LED's, or digital meters. Some newer ones, such as the Outback FM60/80 and others now have built in computer interfaces for monitoring and control. The simplest usually have only a couple of small LED lamps, which show that you have power and that you are getting some kind of charge. Most of those with meters will show both voltage and the current coming from the panels and the battery voltage. Some also show how much current is being pulled from the LOAD terminals.

All of the charge controllers that we stock are 3 or 4-stage PWM types, including the MPPT units. (in reality, "4-stage" is somewhat advertising hype - it used to be called equalize, but someone decided that 4 stage was better than 3). And now we even see one that is advertised as "5-stage"....

How Does a Charge Controller Works

A solar charge controller is an important system component that regulates the voltage generated by solar panels. Charge controllers help to properly maintain your solar power system batteries by stopping them from being over or under charged, and they help ensure maximum battery life. Considered to be among the best in the industry, Xantrex Charge Controllers manufactures only the highest in quality and reliable components. Blue Sky Energy offers charge controllers for rv and marine solar battery charging applications.

You may not always need a charge controller. It depends on the size of your solar power system. Generally, 1 to 5 watt systems designed for trickle-charging batteries will not require one. A general rule of thumb is if the panel's output is less than 1/60 of the battery's rated charge capacity, you probably will not need a charge controller.

The solar charge controller regulates the 16-20 volt output of a typical 12 volt solar panel, reducing it to only the voltage required by the battery to keep it at maximum operating level. This voltage will typically range from 10.5 to 14.6 volts, depending on the type of battery, the temperature of the battery and the state of battery's charge at any given moment.

There are all kinds of charge controllers and they come in all shapes and sizes. They range from 4.5 amp units all the way up to the 60 amp programmable units with computer interface. Most controllers come with either a simple LED or digital displays. Some charge controllers now have built-in computer interfaces for monitoring and control.

How a Maximum Power Point Tracker Works

The Power point tracker is a high frequency DC to DC converter. They take the DC input from the solar panels, change it to high frequency AC, and convert it back down to a different DC voltage and current to exactly match the panels to the batteries. MPPT's operate at very high audio frequencies, usually in the 20-80 kHz range. The advantage of high frequency circuits is that they can be designed with very high efficiency transformers and small components. The design of high frequency circuits can be very tricky because the problems with portions of the circuit "broadcasting" just like a radio transmitter and causing radio and TV interference. Noise isolation and suppression becomes very important.

There are a few non-digital (that is, linear) MPPT's charge controls around. These are much easier and cheaper to build and design than the digital ones. They do improve efficiency somewhat, but overall the efficiency can vary a lot - and we have seen a few lose their "tracking point" and actually get worse. That can happen occasionally if a cloud passed over the panel - the linear circuit searches for the next best point, but then gets too far out on the deep end to find it again when the sun comes out. Thankfully, not many of these around any more.

The power point tracker (and all DC to DC converters) operates by taking the DC input current, changing it to AC, running through a transformer (usually a toroid, a doughnut looking transformer), and then rectifying it back to DC, followed by the output regulator. In most DC to DC converters, this is strictly an electronic process - no real smarts are involved except for some regulation of the output voltage. Charge controllers for solar panels need a lot more smarts as light and temperature conditions vary continuously all day long, and battery voltage changes.

Charge controllers explained by Abie Newenergy

Charge controllers or voltage regulators protect the batteries from overcharging, subsequent gassing, loss of electrolyte and possible plate damage. By monitoring battery voltage they regulate the charging current from the PV array enabling batteries to be charged but not over-charged. They also contain suitable protection to prevent any current drain from battery to PV array eg. at night.

This is usually best done by gradually reducing (or tapering) the flow of energy into the battery as a full charge is reached so achieving a more complete charge. Very fast solid state switching technology is used for this known as pulse width modulated (PWM) control.

Some controllers also include a low voltage warning or disconnect function to switch off loads if the batteries become very low preventing excessive discharge. Optional displays indicate charging currents, load currents and battery voltage, or separate meters and system monitoring can be used.

In choosing the the proper charge controller the main consideration is the peak charging current
you need to regulate. It is worthwhile selecting one that will handle extra power if needs change in the future.

Controllers should not be used with more modules than they are rated for. However, a PV array can be split into sub-arrays each with it's own charge controller, in order to accommodate increasing numbers of modules. For the smaller output panels, or where a relatively large battery store is used, regulators may not be necessary.

All controllers listed include blocking diodes or other protection to prevent any current drain from battery to PV panel at night, so no additional blocking diodes are required.
