For off grid / solar power systems, it is usually much better to charge the batteries are around a 10% to 13% or so rate of charge--Simply, because the sun is not up in the sky long enough to fully recharge a well discharge battery bank at 5% rate of charge....
Battery capacity, also known as energy capacity, is the ability of a battery to deliver a certain amount of power over a while. It is measured in kilowatt-hours (product of voltage and ampere-hours) and determines the energy available to the motor and other elements.
If you want to power several smaller devices, choose a battery with a higher capacity and lower power output. If, however, you have larger appliances you want to keep running, like air-conditioning and medical equipment, choose a battery with a lower capacity but higher power output.
Whereas batteries with a lower capacity but higher power rating can run your whole home, but only for a few hours. This is the maximum amount of electricity your battery can continuously supply over an extended period. It's important because it indicates how many appliances can run at the same time from your battery.
On average, this works out at just under 5kWh per day. Mark has neither the financial nor practical means to install renewable technology. However, he can use a home storage battery to take advantage of cheaper off-peak electricity rates, perhaps with the likes of the Octopus Flux tariff. Due to its compact size, Mark opts for the Giv-Bat 2.6kWh.
Working with a reputable installer with a strong track-record will ensure your battery system is optimized to meet the energy needs of your household. When you're ready to make a decision, a Panasonic-authorized installer can help you pick the best battery for your home.
