There is much to consider when choosing which kind of Emergency Backup generator and power supply generator you need during a power outage or when you use off-grid back up power. To determine a back up power generator system, uninterruptible power supply, or a battery is right for your home, you need to know the pros and cons of emergency generators or home battery back up systems for your home or office to maintain power supply until utility power is restored.
You’ll also need to consider whether you want to buy a gas generator, diesel generator, air or liquid-cooled, fixed standby generator, or a portable generator. Do you want a seamless switch to emergency battery power, fed by solar, or will a portable air-cooled generator fulfill all of your needs?
Comparing the differences between a Emergency Back Up generator and power generator for your home power supply can be less of an onerous task if you have first carried out a detailed energy audit so that you know how much power you will need during a power failure.
How much power does your home need?
To work on how powerful your battery back up system, standby power system, or home backup generator needs to be, carry out an energy audit by calculating how much power your appliances use. once you have the details from your energy audit, you can decide to choose which system will be best for your home or office and whether you prefer a battery backup system or a generator.
Key differences between battery backup systems and generators
If you choose to have a generator instead of a battery backup system, there are standby generators, air-cooled generators, and liquid-cooled generators, with a range of fuel options. Each has its own benefits and disadvantages that should be taken into account before you decide which system is right for you. There are pros and cons for each type of generator or battery system. check whether in your state you need a permit for your generator, remembering that your local regulatory body might have other options that apply.
Which system is best for your specific scenario?
You need to decide whether to buy an Emergency Back Up generator or power generator, then drill down into which generator or battery system to use. Your decision should depend in part on where you live.
If you live in an area with long-cold winters, bear in mind that battery systems do not perform well in very cold weather. cold can reduce the ability of a lead-acid battery to transfer full power to where it is needed, and it can lose up to 50% of its power. Lithium-Iron phosphate battery electrolytes can freeze at temperatures of -40 degrees c and should be charged when the temperature is above 32 degrees F. Lithium-Iron phosphate batteries are your best choice in cold weather (above – 20 degrees c), but will still suffer up to a 10% loss of capacity. consider a standby generator that is liquid-cooled and has a propane tank.
If you live in an urban area, noise is a huge factor in your choice. air-cooled generators are significantly noisier in operation than liquid-cooled generators and might upset the neighbors. Lithium-Iron phosphate battery systems alco have low levels of noise when in use. consider a battery system with solar pV if you get enough sunshine.
If you live in an area when power outages happen frequently and the power stays off for an extended period of time, then a liquid-cooled generator that is fueled by either liquid propane or natural gas is your best option. Gas-fueled generators burn cleaner and tank leaks are rare. avoid vapor propane if you live in a cold area. The surrounding air must be warm enough for vaporization to happen, and getting the correct amount of gas to the generator might be an issue. Lithium-Iron phosphate battery systems, if of an adequate capacity, are also an option. consider a standby generator that is liquid-cooled and has a (preferably liquid-cooled) propane tank.
If you live in the pacific time zone, then avoid natural gas for your generator due to the possibility of earthquakes. consider a battery system with solar pv if you get enough sunshine.
