Off grid solar system
Discuss some tips to maintaining Off grid solar system:
Off grid solar system is also known as standalone Solar Systems; this system is totally independent of any electric utility grid.
In off-grid solar powered system, how much power you can run, it depends upon power of Inverter and it’s competence, usually all inverter arises with 80% efficiency, so, if you buy 3 kw Inverter system then up to 2,400 watts of peak power you can run at set point of time. Running air-conditioner and submersible can be classy for you.
Off Grid Solar Systems are used to assemble and store solar energy to be used by household appliances. This type of systems naturally generates from 100 Watts (very small systems) to 5 kilowatts (larger systems, multi-family homes).
Tips to Maintaining an Off-Grid Solar System
The main part of maintaining an off-grid solar system is taking good care of the battery bank. So it can extend the life of your batteries and cut down the long-term cost of your RE system.
- Check the charge level
The depth of discharge mentions to how much a battery has been discharged. The state of charge is precisely the opposite. If the depth of discharge is 20% then the state of charge is 80%.
Discharging the battery by extra 50% on a regular basis can shorten its lifespan so do not let it go beyond this level. Check the exact gravity and voltage of the battery to determine its SOC and DOD.
You consider to use an amp-hour meter to do this. Though, the most accurate way to measure the exact gravity of the fluid inside is through a hydrometer.
- Equalize your batteries
Inside a battery store are multiple batteries with several cells each. When you charging, the different cells may have varying particular gravity. Equalization is a method to keep all cells fully charged. Manufacturers often suggested that you equalize your batteries once every six months.
If you don’t want to regularly monitor your battery bank, you can program the charge controller to periodically perform equalization.
The charger is allowing you to select a specific voltage for the equalization process as well as the length of time to do it.
There is also a manually to determine if your battery bank wants equalization. After measuring the specific gravity of all of the cells using a hydrometer, check if some are significantly lower than the others. Equalize your batteries if that is the case.
- Check the fluid level.
Flooded lead-acid batteries have a mixture of sulphuric acid and water. Such as the battery charges or supplies power, some of the water evaporates. This is not an issues with sealed batteries but if you are using a non-sealed model, you need to top it up with distilled water.Open your battery cap and checked the fluid level. Pour distilled water up until no metal lead surfaces are visible. All batteries have to fill guide so the water doesn’t overflow and spill.
Avoid water from escaping to quickly, replace the existing cap of each cell with a hydro cap. Beforehand you remove the cap, ensure that the top of the battery is clean to prevent any dirt from getting into the cells.
How frequently you top up will depend on battery usage. Heavy charging and heavy loads can end in more water loss. Check the fluid at least a week for new batteries. From there you’ll got an idea of how often you need to add water.
- Clean the batteries
When water escapes through the cap, some might leave condensation on top of the battery. These fluid is electrically conductive and slightly acidic so it makes a small path between battery posts and pull more load than necessary.
To clean battery terminals, mix baking soda with cleaned water and apply using a special brush. Rinse the terminals with water and ensure that all connections are tight. cover the metal components with a commercial sealant or high-temperature grease. Be alert not to get any baking soda inside the cells.
- Do not mix batteries
While changing batteries, each time replace an entire batch. Mixing old batteries with new batteries can decrease performance as the new ones so quickly degrade to the quality of the aged ones.
Well maintaining your battery bank can increase efficiency and extend the lifespan of your off-grid solar system.
