    What is a whole house solar generator?

    This is a solar generator that can supply power to the entire household. A generator is an all-in-one device that brings together various technologies and electrical devices in a single portable unit.

    The components of a whole house solar generator are

    • Inverter
    • Charge controller
    • Battery
    • Solar panels (optional)

    When all these components are put together in a single unit, it forms a solar generator. Solar generators may or may not come with solar panels. However, some manufacturers offer solar generator kit that includes compatible solar panels and generators. If they are not included, you will have to buy suitable panels separately.

    Solar generators are also known as solar power stations and solar power boxes. 

    Why should you choose a whole house solar generator?

    If you are not expert enough to understand, buy, and assemble various components of a solar system, solar generators are excellent choices. It will make it easier for you to enjoy the benefits of a solar system without the hassles of figuring out the right components for your solar panel system.

    With a solar generator, you can also avoid the trouble of connecting the components. If your knowledge of electrical wiring is limited, you will find this an attractive choice.

    Here are a few more reasons why you should choose a solar generator.

    Solar generators are silent and don’t pollute. This is in comparison with your only other option – a diesel-powered generator. They emit carbon dioxide, a greenhouse gas besides toxic fumes and high noise levels. 

    Solar energy is clean, green, renewable, and sustainable. Whether you are using grid energy or using a diesel-powered generator, the energy comes from burning fossil fuels, which is not clean, green, renewable, or sustainable.

    Solar generators offer an uninterrupted power supply. This means whenever there is a power outage, the generator turns on on its own and starts generating electricity to meet the demand. The generator will also shut off when the power comes back. 

    Solar generators will have sufficient power to meet all your energy needs. As this device is designed for this purpose, you won’t feel the annoyance of the power outage anymore.

    Solar generators demand less maintenance. As this device doesn’t have moving parts, wear and tear is minimal. You just need to ensure that the generator is topped up.

    Solar generators are customizable. They allow you the flexibility to add more devices to make them suitable for your needs.

    Solar generators come with compatible components. You don’t have to invest your time in understanding them and shopping for the right solar energy devices to make them work.

    Solar generators are easy to install. Most of them come as plug-and-play devices. 

    Solar generators are portable. Unlike the typical solar energy systems installed at homes, these are just plugged into your electrical system and not fixed. Moving them is easier.

    Can a solar generator produce power for a whole house?

    The simple answer is yes if you choose a suitable one.

    Here are a few pointers to pick the best solar generator for home use.

    Sufficient battery capacity: The capacity of the battery (given in watt-hours or amp-hours) should cover your energy requirements. A solar generator with insufficient capacity won’t be able to meet your energy needs.

    Sufficient inverter capacity: The power output of the inverter (given in watts) should be able to meet your energy demand. A solar generator with an inadequate inverter may not function at all. 

    The capacity of the battery and inverter are the two most important aspects to consider when picking a solar generator for house. To ensure that they have sufficient capacity to meet your energy needs, you first need to have a good understanding of your energy needs. 

    How to determine the capacity of a solar generator for your home?

    Your energy requirement needs to be measured on two levels.

    1. Your energy usage per day
    2. Your peak-hour usage

    First, to know your per-day energy requirement, you can get it from your past energy bills. For more accuracy, you can take the average monthly energy consumption for the past 6 months or one year. Once you have your monthly consumption, divide it by 30 to get per-day consumption. In the US, the average per day consumption is in the range 15-30kWh.

    Second, to know your peak hour usage, list down the power consumption of all your energy-guzzling devices. Add it up to get the power output needed for your home. In the US, the maximum load in an average household is 3-5 kW.

    With this information, you can calculate the capacities of your battery and inverter.

    Battery capacity depends on how long the battery should supply power when the sun is not shining. In sunny locations, the solar battery will get recharged during day time every day. So you need to consider only the night hours for this calculation. If you live in an area where rains and cloudy days are frequent, you have to account for this as well. 

    The capacity of the inverter should ideally be 120% of the power output needed to run the house. If your maximum load is 5kW, the inverter capacity needs to be 6kW.

    You also need to know how many solar panels you need to support this solar generator. You can calculate this by dividing the battery capacity by the product of the wattage of individual solar panels and peak sun hours in your location.

    Solar system or a whole house solar generator – Which one is better?

    There is no right answer to this question. It depends entirely on your situation and requirement. 

    If you have limited knowledge about your power consumption, capacities of electrical devices, and electrical wiring, a solar generator is a good choice. It is a plug-and-play device that requires no in-depth knowledge. It’s easy to monitor with a single app. Moreover, it also comes with the additional attraction of portability. 

    However, the traditional solar system comes with its own advantages. It may require some electrical knowledge on your part for shopping, setting up, and maintenance. But with this, you can customize the system to your requirement. Most often, this comes cheaper if you know the ins and outs of the components and where to get it cheap.

    How to shop for the best whole house solar generator?

    Once you have the minimum capacities of the inverter and battery for the solar generator and the number of solar panels needed to ensure sufficient solar energy, you are ready to go shopping. One word of caution before you buy a whole house solar generator.

    When you are buying an electrical device, it would be advisable to consider the Levelized Cost of Storage (LCOS) rather than the actual cost. LCOS is the cost of the storage device after accounting for the cost of electricity discharged from the storage device throughout its lifetime. This means a low price tag is not always desirable. If the device is incurring a loss of energy or doesn’t last long, its LCOS will be higher than a higher-priced device.

    In simple terms, this means you should consider the quality of the product and not just its price.
