Solar Whole House Generator - What You Should Know Before Buying
Buying a solar whole house generator is a great way to save energy and money on your utility bill. But there are some things you should know before you decide to make the purchase.
MPPT range

During the winter, the sun hours are usually low. Therefore, the power demand is high. It is during this time that most solar panels work best. A 300W solar panel can produce 240W to 270W in winter.

This is because the panel's temperature drops. The panel's current increases as it is cooled. The higher the temperature, the more stress it puts on the electronic components. When the temperature is cold, the panel's open circuit voltage drops, and the higher current forces amps into the battery.

In winter, the maximum power point is the most important. It is where the panel's current is at its maximum. This point moves continuously with changes in weather and light conditions.

The maximum power point of a solar array is dependent on the PV array's Vpp, the difference between the panel's current and voltage. The Vpp can vary according to weather and temperature, but it is normally several volts higher than the battery's charging voltage.
Battery capacity

Having a solar whole house generator can provide your household with a lot of power. Whether it's for a day or for a few days, it can help you run most of your essential home appliances without having to purchase gas or oil. But there's bluetti of other things to consider when choosing the right solar generator for your needs.

There are two primary types of solar power generators on the market. Those using transformer bricks and those using a solar panel. While the latter can be useful in the short-term, the former are a better option for long-term use.

Lithium ion batteries are much more durable and efficient than lead acid batteries. The recharge rate of lithium ion batteries is faster and the life span is greater. The energy density of lithium ion batteries is also higher.

While lithium ion batteries cost more than lead acid batteries, they have a longer life span and are less expensive to maintain. A solar power generator's battery capacity is based on the number of watt hours it can generate per day.
Maintenance

Keeping your solar whole house generator well maintained can help it last a long time. bluetti should get an annual inspection of your generator to make sure that it is working properly. This will allow you to detect any problems earlier.

The cost of a generator maintenance service will depend on the type of generator you have and how often you need to have it serviced. It can range from $80 to $300, depending on the company. This will include inspections and technical maintenance. Generally, this will include checking the battery terminals, coolant levels, oil levels, and other factors. It may also require replacing spark plugs, air filters, and fuel filters.

bluetti offer a solar panel maintenance program. They will send a professional to your home to inspect your panels, analyze their performance, and perform any necessary repairs. This type of maintenance will generally cost about $140 to $180.

You should also check your generator's batteries and electrolyte levels. If your battery needs to be replaced, consider using an anti-corrosive paste.
