For lead-acid battery charging rooms and other areas where hydrogen is present protects life, property and profits. The size of the area one detector will protect depends upon the battery compartment or room. Automatic Operation, Continuous Monitoring, High Sensitivity & Stability, Solid State Reliability, Safe, 12 Volt dc Operating Voltage, Easy Installation, Low Cost, Two Year Warranty.
The sensor consists of a semiconductor whose electrical conductivity increases when hydrogen is adsorbed on its surface. Remote box (modular jack with duplicate LEDs, test button, and buzzer if needed) for placement at eye-level or in another room. Batteries and other energy storage devices store energy so that it can be used when needed. Any renewable energy system also includes switches, circuit breakers and fuses to ensure it is electrically safe and allow major equipment to be isolated for maintenance. A grid connected renewable energy system converts DC electricity from a power source, such as solar panels, to AC mains power and feeds it into the grid.
If there is a mains grid power failure, a grid connected renewable energy system disconnects from the grid and energy from solar panels is not available. Battery banks connected to the grid, with an appropriate inverter, may work as an uninterruptable power supply to make energy available during a power outage for all or some of the electrical loads in a home or business.
A stand-alone power system is used for supplying energy at regional and remote locations where it is more cost effective to have on-site generation than to connect to the electricity grid.
A stand-alone power system is used for supplying energy at regional and remote locations where it is more cost effective than connecting to the electricity grid. The exact equipment needed to convert and store energy depends on the energy needs and budget of the user, as well as the available energy resource and physical constraints of the site. The two types of lead-acid batteries that use an acidic electrolyte are wet cell and sealed.
If a battery bank capacity is large enough and usage is low (less than 10% capacity per day), battery life should be at least 10 years. Some electric vehicle makers are looking at making their car charging devices ‘bi-directional’.
Batteries emit a corrosive and explosive mix of hydrogen and oxygen gases during the final stages of charging, which can ignite if exposed to a flame or spark.
Because the gases rise, ventilation design must permit air to enter the enclosure at the base of the batteries and exit at the highest point. Ventilate naturally by allowing the gas to rise and escape safely or by installing fans and electrical vents. Mount batteries on stands to keep them clear of the ground; otherwise, they need to be thermally insulated from the ground temperature.
Battery banks for stand-alone systems can be large and heavy, often requiring 1–5m2 of floor space and weighing hundreds of kilograms. Batteries can be as high as 70cm, and if installed in a box it must be one with a removable lid or at least 50cm clearance above the batteries to allow for a hygrometer to check the charge level.
Limit access to the battery room or container to people trained in maintenance and shut-down procedures. The installation must include a switch or quick-disconnect fuse near the batteries so the bank can be electrically isolated from the rest of the system. Battery maintenance includes keeping terminals clean and tight, and ensuring the electrolyte is kept above minimum levels. Lead-acid batteries hold a liquid electrolyte with sulphuric acid which can cause serious burns.


Specific gravity readings are the most accurate method for determining the state of charge of cells in a battery bank. System owners should read and fully understand the manufacturer’s manual for their battery bank. Inverters are commonly a part of both grid connected and stand-alone renewable energy systems.
Inverters convert DC power from batteries or solar modules into usable AC power, normally 240V AC (single phase) or 415V AC (three-phase).
Inverters can become very warm when operating at large power outputs and need suitable ventilation and cooling airflow.
Inverters should be installed out of direct sunlight as direct exposure can cause them to overheat.
Grid connected inverters convert power from solar panels, wind turbines or micro-hydro systems into AC power. The AC output of the inverter connects with the building switchboard in accordance with regulations and standards. Battery charging is needed in stand-alone systems when the energy from the renewable sources is intermittent.
Connecting an unregulated charge source such as a solar panel directly to a battery without an appropriate charge controller is dangerous and risks permanently damaging the battery.
If a stand-alone power system is installed with a separate battery charger, it should be treated like an inverter.
If the generator is automatically started by other equipment, it must carry appropriate signs and the auto-start system must have an isolator to disable it during repair.
In a stand-alone power system, the energy stored in batteries can be used when energy demand exceeds the output from renewable energy sources like solar (e.g. An inverter in a grid connected renewable energy system converts direct current (DC) electricity from solar panels or a wind turbine into alternating current (AC) mains power. Stand-alone power systems typically include a power generation source like solar panels or wind turbines, a battery bank, inverter, battery charger and often a fuel generator for back-up power. In a stand-alone system, battery banks and inverters are needed whether the energy comes from solar, wind or micro-hydro. However, lithium batteries, though more expensive than lead-acid, are becoming more affordable and can have a much longer life. Wet cell use liquid electrolyte; sealed batteries use either a gel or liquid electrolyte absorbed into fibreglass matt.
Battery makers give information on how long their products last and installers should design and install battery banks to comply with standards and maximise battery life.
One is pumped water storage, where excess energy is used to pump water from a creek or dam to a higher level, for example to a large water tank on top of a hill. This means the electric car’s battery charger is also a grid-interactive inverter, so energy stored in the battery can be used in the home or sent to the grid.
They consist of a complete fuel cell and grid connect system in a unit about the size of a washing machine.
How much ventilation is needed increases with the size of the battery bank and the rate of charge. The floor area required may be reduced by using heavy-duty shelves, and some sealed batteries can be safely mounted on their side. When replacing a battery bank, dispose of the old batteries at a battery recycling station or other suitable site. Insects often like to nest in the heat dissipation vents, so site your inverter carefully and check it often.


They should be easily accessible in case they need to be electrically isolated in an emergency. To avoid overheating and voltage drop, the leads must be of an appropriate size and kept to a minimum practical length. The risk should be assessed by the designer and appropriate protection installed if required. They automatically match the voltage and synchronise the frequency so that it can be fed into the mains grid. The inverter can be installed in any suitable place between the energy source and the switchboard.
Automatic controls start a generator when the batteries reach a low charge level and, with inverters that have genset synchronisation, when the load is greater than the maximum power output of the inverter. If it must be in the same room as the rest of the system, locate it as far away from other components as possible and cover it with an enclosure ventilated to the outside. This is more of an issue for stand-alone power systems with a low proportion of energy from renewable sources, requiring the generator to run more often to meet energy needs. Nickel iron batteries are harder to find and less efficient than lead-acid or lithium ion but have very long lives. Batteries can be supplied as a mono-block but usually come as individual 2V cells which are assembled into a complete battery on site.
Wet batteries are typical for renewable energy systems but sealed batteries are becoming more common because they are safer and easier to maintain. This opens the possibility of charging a car at night when electricity costs are low and feeding the stored energy back into the grid at other times to offset a house’s energy cost.
The resultant electrolyte stratification is detrimental to a battery’s long-term life and performance. Tools, such as spanners, used on the battery terminals should be single ended and have fully insulated handles.
Acid spilt on the floor or equipment must be diluted with water and neutralised with sodium bicarbonate. The equalisation charge is controlled automatically by the system or requires the owner to connect a generator and battery charger at regular intervals (about once a month).
On the DC side, the grid inverter is connected directly to the renewable energy charging source.
When the generator starts, the inverter-charger switches the load to the generator and becomes a battery charger, recharging the batteries from the generator.
This helps stop overheating and fumes from a malfunctioning exhaust as well as reducing fire risks from fuel leaks. Flow batteries (zinc bromine and vanadium redox) and flywheel batteries can be used in renewable energy systems but are complex and expensive. This set-up is generally inefficient but can be much cheaper than battery storage in some places, and is possibly of lower environmental impact because chemicals and metals in batteries aren’t used. No cars have this capability yet in Australia, but it is likely to become common in the future. Keep all personal protective equipment and other safety materials easily accessible at all times and stored near the battery bank.
Battery banks should provide a number of days’ energy reserve — three to seven days is typical.
