Inverters

What is an inverter?

A solar inverter is one of the most important elements of the solar electric power system. It converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into alternating 240V current (AC). This AC electricity then can be fed into your home to operate your appliances.

The electricity that is not used in your home is then either fed into the grid (electrical power lines) or into home battery storage. New hybrid inverters include an integrated battery management system.

Long lasting solar power systems require a high quality inverter with a robust convection cooling system. Low quality inverters have unfortunately failed in the Australian climate.

REGULATORS

Regulators

What is a regulator?

A solar regulator (also known as a charge controller) is used in conjunction with a stand alone (off grid) system, or a grid connect solar power system that incorporates a backup battery bank. For a grid connect solar power system that doesn’t use batteries, a solar regulator is not needed.

A solar regulator is a small box consisting of solid state circuitry that is placed between a solar panel and a battery. Its function is to regulate the amount of charge coming from the panel that flows into the deep cycle battery bank in order to avoid the batteries being overcharged. A regulator can also provide a direct connection to appliances, while continuing to recharge the battery; i.e. you can run appliances directly from it, bypassing the battery bank; but the batteries will continue to be charged.

Modern solar regulators are very efficient and will outperform just about any 3 stage mains power battery charger.

PUMPS

Solar Pumps

Solar pumps are an energy efficient, environmentally friendly way to pump water for a variety of domestic and commercial purposes, including agricultural and residential irrigation and cattle or livestock watering. Solar pumps are easy to install and require virtually no maintenance, and they can have a lifespan of roughly 20 years, so after the initial set up costs their servicing requirements are virtually nil.

SOLAR PANELS

Solar Panels

A 5kW solar system may produce enough energy to power your home, but you may not have enough roof space for a system of that size. Solar panels for households typically come in the standard dimensions of 1.70m x 1.00m, that’s around 1.7m2 for every panel installed. However, the wattage output (W) of the panels will likely vary between 250W and 330W for a more efficient module.

As a guide, you’ll need 4 x 250W panels, or 3 x 330W for every 1kW of your solar system. If you’re considering a 5kW system, that’s between 15 and 20 solar panels that will require anywhere between 25.5 – 34m2 of roof space.

SOLAR HEATING

Solar Heating

How does a solar thermal system work?

A solar thermal system consists of a number of components; a solar collector, a pump, a controller and a hot water storage tank.

The solar collector, located on the roof, collects the sun’s energy and transfers the heat to the storage tank. The storage tank allows the hot water to be stored until it is used at night or in the morning.

Solar geysers can be divided into two primary types:

  • Direct systems that pump water into solar panels, which is then heated and stored in the geyser. They can use either solar panels or evacuated tubes.
  • Indirect systems use a specially designed type of anti-freeze, which circulates through solar panels to heat the water, which then flows to a geyser. They also operate with solar flat plate or evacuated tubes.

LOW & HIGH PRESSURE SYSTEMS

Low Pressure systems are designed to use gravitational pressure from the water level in or above the tank. (or on a farm dam).

A low pressure solar water geyser is classified as a “NO” pressure solarwatergeyser. … All and all the difference between a “NO and “HIGH” pressure solar watergeyser is that the “0” pressure system cannot handle pressure at all and the high pressure system can handle high pressure.

GEYSER ROBOT

The GeyserRobot is a smart switch which turns any standard geyser and element into a solar geyser using PV solar panels. The PV solar panels are directly connected to the GeyserRobot which directs it to the geyser element. The GeyserRobot comes standard with a digital display and thermometer which replaces the geyser thermostat. This full automation of your heated water needs. Whenever the geyser water has obtained the pre-set temperature on the thermostat, the GeyserRobot will switch off the geyser element.

At any time, the geyser could be switched back to grid power when insufficient heating is obtained from the sun (in case of cloudiness or increase usage of hot water from the geyser). In this case, the element and thermostat will function as normal.

BATTERIES

Solar Batteries

Solar Batteries are batteries necessary for the function of certain types of solar panel systems. Deep Cycle Batteries are also known as Solar Batteries which play a crucial role in stand-alone renewable energy systems.

If you require a battery to operate a solar panel, wind or even a hydro-electric system secured to your utility grid, you will need a Solar Battery – this is especially pertinent when there is a power outage and could prove to be particularly handy with the copious amounts of load shedding that we are being faced with.

  • Solar Batteries will provide the energy to your renewable energy system, unlike car batteries.
  • Solar Batteries are meant to be discharged and cycled constantly.
  • For batteries to enjoy longevity most manufactures recommend that the depth of discharged of these batteries is limited to 20% – in other words the Solar Batteries will be at 80% capacity or more.
  • It is important that the batteries are not discharged below 50% Depth of Discharge.
  • Inverters usually have Low Voltage Disconnect features that will disconnect loads at certain points.
  • Low Voltage alarms can also be installed.
  • To maintain your battery, Ammeters, Voltmeters as well as Battery Monitors all play an integral role in upholding the health of your Deep Cycle Batteries, and the complete power system as a whole.
