Best Solar Generator Kit Reviews – Guide & Chart

You may have thought about bringing your energy consumption down by taking advantage of a natural power source: the sun. Not only can you store and convert something free into something usable, but you’re also reducing carbon emissions and energy waste.

The Best Portable Solar Power Generators & Power Station

Emerging technologies include generators that store and run on solar power. If you’re away from home, you don’t have to rely on traditional power or fuel. All you need is a reliable solar-powered generator that stores solar power while you do other activities.

What Are Features of a Solar Generator?

A solar generator typically consists of the following:

  • Solar panels that harness the sun’s energy and convert it into electricity. These are made up of interconnected photovoltaic cells.
  • A battery to store the electricity until it is needed to power or heat a unit.
  • An inverter to convert energy stored in the battery from DC power to AC power. It also amps up the voltage depending on the needs of the unit that needs to be powered.

Key Elements to Consider When Purchasing a Solar Generator

There are five elements to check when looking for the right solar generator. An understanding of each will give you a better grasp on how they can work to your advantage and at what capacity they should be functional.

Energy Storage Capacity

An important feature is a generator’s capacity to store energy. It has to be reliable after the sun sets, when energy required can’t be replenished until the sun returns.

To measure this, calculate the battery’s capacity. Identify its voltage (in volts) and amp hours (Ah). For example, a 12V battery might be rated at 150 (Ah). Compute the watt hours by multiplying the volts (V) by the amp hours (Ah), then dividing by 100. This lets you know how much energy the battery provides.

However, most manufacturers won’t recommend that you drain a battery because it can lead to a shorter life cycle. To preserve your battery, avoid draining it to zero capacity.

Solar PV Input

The photovoltaic (PV) input of the panels determines how long it takes for batteries to charge during the day or how much energy is transferred to the battery for storage during charging periods. For example, a solar generator with PV panels at 300 watts can convert that much into the battery while under full sun. It is best to have a PV input rate equal to or greater than the battery capacity.

Since the sun is not uniformly bright every hour, expect the PV input to be lower than usual at certain hours. However, PV panels with solar tracking or the ability to change position based on where the sun is to have a higher chance of filling a battery faster. It’s safe to say that the sun is at its brightest six hours in a day, so the optimal charging period is 6 hours. Anything more can affect a generator’s usability during other parts of the day.

Inverter Rating

Batteries power devices using direct currents (DC). However, most devices run on alternating currents (AC). For stored energy to be compatible with regular devices, it needs to be convert from DC to AC and then further convert the low battery volt into the appropriate AC voltage. This could either be 110V, 120V, 220V, or 240V.

The inverter rating tells you how many watts you can pull from the generator at any time. Some buyers use this as the baseline in determining if the generator is strong enough for their home. However the optimal ratio of battery to inverter rating is 1.5:1. This makes sure that you’re not depleting the battery to the max, which could mean a shorter lifespan and quicker energy depletion. For example, if you have a battery rating of 1500 watt/hr, your inverter should be at least 1000 watt/hr.

Portability and Component Quality

  • Will you be going off-grid and need a stronger generator to power your entire home or office until the evening?
  • Will you need an emergency backup power supply?
  • Will you be using it during big events only or during large projects like construction work?
  • Will you be using it in outdoor activities like road trips, camping, or hunting?

Size and weight factors heavily in this decision, and so does the amount of noise produced while discharging. Some generators can be easily wheeled away, others need a flat surface to be mounted on, and others can be placed just about anywhere. As mentioned before, solar panels can be stationary or move at an angle to track the sun. Take into account if you have sufficient space for additional features like these.

Also consider the materials used in the generator. Plastic is lighter and protects it from rust, but ensure whether the plastic components are durable enough. Some generators have casings that’s more reliable against wear-and-tear.

Batteries also come in different forms. A lead-acid battery costs less, but may require more maintenance, such as ensuring only 2/3 of its capacity is consumed every time to avoid decreasing its lifespan. Its voltage also tends to drop during usage, and expect the generator to be heavier.

A lithium battery is lighter with a longer lifespan, but is quite expensive. It doesn’t require maintenance like a lead-acid one, and can be drained down to as low as 10% capacity to maintain optimal lifespan. Charging and discharge is more efficient and more consistent, and it’s 2-3 times lighter than lead-acid.


A well-balanced generator system allows you to maximize charging and usage time without sacrificing either. After learning the key parts of a generator and their respective features, you can make an informed decision on which generator can provide you with sufficient energy when you need it most.

Always remember these three factors:

  • Only 2/3 of a lead-acid battery’s maximum capacity should be used. A lithium battery can be drained down to 10% capacity.
  • The PV input rate must be equal or greater than the battery rate.
  • The ratio between battery rate to inverter rate must be 1.5 to 1.

Down To You

A solar generator works by harnessing energy from the sun through solar panels, then storing it in a battery for later use. The utility or device to be powered is attached to the generator, where energy goes through the inverter and converted into a compatible electric current that runs through the device, your house, or office.

Having a portable solar generator allows you the comfort of electricity even while away from home or any outlet. Whether you want to charge a few gadgets or to power up a mobile home, portable solar generators are a smart purchase that pays for itself over time. Hospitals, schools, and offices have started to invest in solar generators for energy conservation and emergencies.

With the growing trend of sustainable power sources making this easily available, it is a great addition to your home or outdoor gear.
