Inverter Battery Maintenance Tips for Better Performance

Inverter Battery Maintenance Tips for Better Performance

A good battery is the backbone of an inverter and is expected to perform better for a long time. The life of an inverter depends on the quality and maintenance of the battery. And to look at how many times you maintain your appliances, Regular maintenance is not required, but timely maintenance is necessary for effective operation and long life.

When you are going to buy the best quality inverter on the market, pay attention to ampere and guarantee duration. Don’t be in a hurry and pick up any random battery. Consider the battery's work life, or how long it will last. Proper maintenance at the appropriate time enhances the lifespan of inverter batteries.

Tips for maintaining Inverter Batteries

Here are some tips that will help to enhance the lifespan of inverter batteries:

1. Corrosion and rust-free

Rusting in terminals slows the current flow to and from the battery. The limited flow of current results in slow battery charging and a decrease in battery life. Eventually, it affects the inverter backup.

If corrosion rust appears, pour the hot water and baking soda solution on the area. With the help of a toothbrush, rubbing will help to remove corrosion.

Keep the battery in a dry place to avoid rust and corrosion. Apply petroleum jelly to the terminals.

2. Cool place 

Routine usage of inverter batteries keeps them charged and powered. In case you don’t have any power cuts, discharge the battery completely once a month. And then charge it again; it is essential to charge the inverter battery properly to maintain the backup time.

3. Usage regularly 

Inverters must be installed in a well-ventilated area. During charging, the inverter battery gets heated up. A cool temperature reduces the heating up of the batteries. The surface and sides of the inverter battery should be clean and rust-free. Cotton cloth is ideal for cleaning the surface.

4.  Battery water level

It is essential to determine the battery water level every two months. Ensure the water level is between the recommended and actual levels. Energize the battery with distilled water only. The usage of tap water or rainwater affects the life and performance of batteries. This type of water contains an excess of minerals and impurities.

5. Replacement 

If the inverter batteries are worn out, it's time to replace them with new ones. With time, the battery loses its capacity, reducing the backup. Buying quality batteries guarantees their long life and correct charge storage capacity. Poor-quality batteries fail prematurely and are unable to offer sufficient backup.

6. Thermal Environment 

Maintain a good distance between the battery and the fire/Smoke. These small things will help you enhance the battery's capacity and save it from any explosions.

7.  Extension of load capacity

Determine the proper loading of devices. Connection of heavier loads than what the inverter was designed to carry will stop or break the inverter. Power inverters use the energy stored in batteries to supply current to the devices. This makes them keep running during power cuts. High loads or devices used during the power failure will drain more power from the batteries and shorten the backup period. Cut the extra load that is not in use.

The Water level of Inverter Batteries

If you have been using inverters for a long time, you must know about distilled water. You can get this water from local battery stores. If you fail to find them in local stores and want to know more about the water, Google it.

You have seen a cell on an inverter battery; it is a water level indicator. Two marks—green and red—on it define the battery condition.

1. Green Mark: This mark refers to the water being fully topped up and there is no need to do anything. Water should not be above the green mark; more water than required is not good for the battery.

2. Red Mark: This mark refers to the level of the water is decreased. And the need to fill the inverter battery cell with water. Make sure you fill-up the green mark.

How do you fill-up the water in an inverter battery?

  1. Switch off the inverter and also unplug it. The inverter must not get any power from the electric source.
  2. Safety and cleanliness are necessary; wear rubber gloves.
  3. The cell needs to be filled; take off the float indicator of the cell.
  4. Use a cotton cloth to clean the area and float the indicator.
  5. With the help of a funnel, pour the distilled water into the battery.
  6. Put back the floating indicator and tightly close it.
  7. Inspect the indicator level and make sure it's up to the green mark.
  8. Each cell needs to be refilled with water over time.
  9. Switch on the inverter and plug it in.

Inverters have to be regularly inspected

Here are a few tips to help you know how inverters have to be regularly inspected:

1.  Installation 

Mechanical installation is part of the mechanical inspection of the inverter for the solar plants. One of the major factors to check for is the spacing of the installation. Is it installed with sufficient spacing, so that the inverter can be easily accessed? Does it allow for good ventilation around it? Always have multiple structure fitments, as in hooking arrangements or anti-vibration pads.

It is essential to determine if the inverter is accurately fixed to the ground or wall. Either sufficient cooling air can flow around the device, or the components are set up with the correct type of joining. Are the cable gland plates, sides, doors, mounting plates, roofing, etc. intact and free of any damage and scratches that may have occurred during transportation? You should always check that the drive cabinets are cleanly installed, moisture-free, and dust-free. These surroundings enable cleanliness and the circulation of dry air.

2. Bars 

During standard inverter inspection, bus bars are verified to ensure a sufficient gap between them. They are clean, with no debris, dust, or foreign objects. Adding to it, it is essential to determine if the connections and joints of bus bars are tightened and if their supporter insulators are in good condition.

3. Components 

Inverter maintenance can pose multiple challenges and recurring problems. If the electrical components are not aware of specifications or are not installed correctly. Along with a visual inspection of the situation of each element to ensure there is no damage, it is necessary to document the required number of components, their specifications and ratings, and their make and type. They are best suited for installation; check whether the ingredients are properly labeled and visible for inspection. If the drive modules are properly mounted and securely attached to the plug connectors.

4. Electrical addition 

From the viewpoint of electric installation, there are a few important checks. First, are the power supply cables routed properly or differently? Second, are the AC, DC, and auxiliary power cables tightened and fitted properly? Third, ensure that the assembly insulation is adequate and that the inverter is properly grounded. Therefore, the AC line voltage and inverter match the nominal output voltage. The correct type of AC transformer and specifications should suit the inverter being used.

5. Cabling and Wiring

All the cables must be of the required length and fitted without knowing the difference between the connection points. Requirement of cable glands and gland plates for tightening. Wires can be pulled or tugged; check whether they are securely placed. Check the short links and look at the chaining, then consider them correctly done.

You should check to see if cables are foiled without any of their sections being affected by sharp objects. When there are any bare or exposed areas in the line and blending areas are within desired levels.

6. Earthing and Mechanical Tests

Check mechanically; it includes a cabinet door defeat function test. Simply check to open and close doors to consider they do not grate opposite the floor or other objects. In addition to that, it is vital to determine if the panels are dual-earthed and if the switches function smoothly by switching them. On and off testing to determine how they work. Check all the fuses, whether they are securely fitted or not in the fuse base or socket.
