Choosing the right size depends on the level of energy independence that a renewable energy owner wants. It may simply boil down to what you can afford. These levels range from 100 percent or completely off the grid (the most costly), to a simple energy backup for emergencies.

100% energy independence or completely off the grid: this requires a huge investment in terms of generation and storage. In addition, it may require other power sources such as fossil fuels or wind generators.

High energy independence: This requires a solar system with enough batteries to last a few days or even through the winter. PV systems are sized to enable the owner to have surplus energy to store during summer and be self-sufficient through winter without relying too much on the grid. The customer will still rely on the grid for backup just in case there are prolonged days of bad weather.

Summertime independence: Customer installs just enough panels and storage capacity to get through a normal summer day but will have to draw power from the grid during the winter.

Peak time independence: Battery size should be large enough to supply power during peak times when electricity rates are highest.

Reduced reliance on the grid during peak times: Some customers cannot afford to install enough storage to cover their entire peak time usage. In such a case, some will install a system that will enable them to at least reduce part of their grid usage during these times.

Emergency power backup: This requires smaller energy storage, enough to cover a short power outage. Some customers use this together with fuel generators. Battery storage is only required for the short duration from the time grid power goes out, to when the alternative power becomes available.

Even though a solar energy system is a great investment that reduces your electricity bills, it is not possible to completely get off the grid without investing in large storage systems. However, adding modest battery storage to a grid connected to solar systems is a better way of increasing your independence from the grid without spending too much.

Most marketers have online tools that can help you get the right size battery based on various factors. However, it is advisable to consult professionals for the best advice.

Customers with solar systems are increasingly adding battery storage to reduce their electricity costs or become independent from the grid. With better technology and prices getting lower every day, battery storage is becoming an appealing component to many solar power system owners.

This type of storage allows the customer to charge their batteries during the day and then discharge them when there is no generation. This permits homeowners and businesses to have a backup power source and save on electricity bills. In addition, you can sail through cloudy periods or other times when power generation is low.

Many of us get excited to decorate for Halloween and Thanksgiving, but why should our homes miss out on the sheer delight and beauty of Fall colors for the rest of the season? If you love pumpkins, the warmth of gold and rust tones and ever-changing leaves, consider decorating with autumn-themed accessories this season. Some Halloween decor like brooms, scarecrows, and orange lights represent fall itself and can be extended beyond October decorations. If you’re looking for an understated alternative to ghostly props and frightful window clings, try dazzling your home and your guests with the following fall lighting ideas this year.

If the motor seems to be fine, attempt to reconnect it to a load. For motors spinning in the wrong direction that are three-phase, swap any two leads either in the starter or in the motor connection box to reverse its rotational direction. Motors that struggle with a load may have something plugged up or jammed in the load itself. A mechanic may be required to check fans, belts, or pumps that are powered by a motor. When a motor trips the overload device, attach an anmeter to measure the current during startup and operation. Check the FLA on the motor nameplate to see what the expected current draw should be. If it is high, the motor may simply be overloaded. If not, the overload protection device may be set too low or may need replacing.

By following these basic ac motor troubleshooting tips, any electrician can quickly determine the cause of most problems in an AC motor.
