Size of battery might be estimated based mostly on precise related load and required backup hours. Battery ranking outlined with Ampere Hours (AH). Please go to loom photo voltaic for element battery dimension calculation.

Battery Capacity Calculation Formula:

Battery Capacity = Inverter Capacity & Voltage

The charging present is ready within the battery. It is essential to know what number of Amp’s charger to cost. Each inverter has a given ranking of cost. If we cost the small battery with the charger of most ranking, then the layer of lead which stays on the battery cell will warmth up and fall within the battery and the battery will get broken. When the battery is dangerous, the backup will cease giving and the battery won’t begin charging. Therefore, the capability of the battery is chosen in accordance with the capability of the inverter.

Case 1: Commercial Establishment

In January to March month, energy consumption of any industrial locations, equivalent to workplace, store, college, clinic & hospital, and many others. the utmost energy consumption is 40% – 50% evaluate than summer time season (April to September). When we plan to put in inverter battery, we should know annual energy consumption.

For instance, we’re taking an instance of 1 workplace whereas 50 laptops, 2 desktop, 50 ceiling bldc followers, 60 lights, web, router, cell charging, 1 fridge, 1 water cooler, 1 printer, and 1.5 ton cut up inverter ac, and another lights. During the summer time season month of April, the utmost energy consumption is 4500 watt whereas throughout the winter season month of January, the utmost energy consumption is 1500 to 2000 watt.

Based above energy consumption, now we have chosen 5kVA inverter and this inverter is available in 48V. According to battery capability calculation formular, we’d like right here 48V battery.

How many hours backup required? In case of business institutions, the utmost energy reduce length is as much as 2 hrs. however it’s frequent energy reduce. The energy reduce length is perhaps 5 minutes, 10 minutes, like this. The objective of putting in energy backup resolution in industrial areas to provide uninterpreted energy provide to run industrial actions.

According to steady load and backup time, we’d like 9000 watt hour battery financial institution. If you choose 150Ah lead acid battery, you then want 6-7 batteries and if you choose CAML 100Ah lithium battery, you then want 2 batteries.

Case 2: Residential Places

The identical situation in residential houses however residence home equipment are completely different. The fundamental home equipment of any houses, equivalent to lights, followers, television, washer, fridge, water sump (floor pump / submersible pump), web, laptop computer, energy socket, iron press, air conditioner (regular ac or inverter ac), and extra. The common energy consumption of any house is 300 – 400 watt, however most energy consumption 1500 – 2200 watt of any 3 BHK houses.

If any residence proprietor desires to run solely fundamental home equipment equivalent to followers, television, mild, web, fridge, and energy socket, then he wants 1kW inverter and this inverter is available in 24V. Based on this inverter voltage calculation, he want 2 no. of 150Ah lead acid battery. If he run 400 watt hundreds on residence, then it can provide 6-7 hrs. backup time.

If any residence proprietor desires to run fundamental home equipment in addition to heavy home equipment equivalent to water pump, air conditioner, washer, dish washer, induction, and extra, the he want 3kW inverter and this inverter is available in 48V. Based on this inverter voltage calculation, he want 4 no. of 150Ah lead acid battery. If he desires to put in the most recent expertise battery, then he want 1 no. of CAML100 lithium battery. If he runs 2000 watt load, then it can provide 2 hrs. backup time.

Note: The backup time can differ relying on energy consumption, so above information is just on your concept.
