Frequently Asked Questions

The answer must be home backup battery, and not only that, the FranklinWH  system can provide you control over your home energy, including battery, solar, generator, grid, and even EV, to save your money. That savings extends to participating in VPP and TOU programs in your area.

In most scenarios, you don’t need to buy a generator for your home backup, but it may be an emergency energy resource for your home if you want to plan for longer outages.

Using self-generated clean energy will be the cheapest way. You can install a solar system along with battery storage and that can power all the loads in your home, so you will be able to reduce or eliminate your reliance on grid energy.

This depends on the maximum power input needed for household loads, e.g. to start a 3-ton air conditioner (4 kW), a number of base loads (1 kW), you need at least a 6 kW and above PV system, requiring roughly 20 panels.

Yes, it would store grid energy, and power your home when outage happens or during peak rate hours.

In most cases, battery storage is better than a generator due to its stable current output, but a high-quality standby generator may be better than a lower-quality battery. The disadvantages of a generator for home power backup are that they are noisy, have high fuel costs, and can have poor output current quality, which will cause damage to some household loads.

The brand of both matters, so research is required.

Determining the size of the battery backup you need for your home depends on several factors, including the number of devices you want to power, the duration of backup you need, and your overall energy consumption.

Home backup power refers to systems or devices designed to provide electricity to a home during power outages or disruptions in the main power supply. These systems ensure that essential appliances and devices, such as lights, refrigerators, and heating/cooling systems, can keep functioning when the grid goes down.

For home power backup energy, the best choice is home energy storage batteries, especially those batteries with stable output power and long backup time.

The disadvantages of a generator for home power backup are that they are noisy, have high fuel costs, and can have poor output current quality, which will cause damage to some household loads.

The disadvantages of solar photovoltaic (PV) systems as home power backup include that they can only supply power during the day, and are affected by weather changes which mean variable output power.

Of course, but a bigger issue is what power is required to start the AC, which depends on the LRA value. Air conditioners are surge loads requiring different consumption to start and run. In most scenarios where a battery’s LRA can reach 150 A and the operating power is more than 8 kW, then most of the household AC can be powered.
