Powerzone batteries is a product of Amara Raja Batteries ltd, the makers of Amaron. Powerzone offers optimised range of inverter batteries to suit varying needs/applications of end users, this avoids confusion while choosing the batteries.
Not sure if you are aware of the process involved in Buying Home UPS and Inverter and hence elaborating a bit more than price.
2 critical Elements:
Inverter Sizing - Idenitfying Loads you have. Ex. Lights, Fans, TV, Laptop, Router etc; Pl note Inverters can't operate Fridge, WM, AC's. Pl choose only those are mandatory that you should use. Remember battery is a limited source of supply unlike the main power line.
Watts Qty Total
Normal Tube Light 40 Watt X Qty
CFL 20 Watt X Qty
Fan 60 Watt X Qty
Laptop 200 Watt X Qty
Router 100 Watt X Qty
Total Load
Factor of safety 20% more
Home UPS Range : 675va. 950va, 1250, 1400va . 1400Va operates on 24v and hence needs 2 batteries and is used for houses that need more back up power.
Battery Sizing - You should have a clear idea reg no. of hours back up you are expecting. Total wattage of your loads multiplied by no of hours you expect the back up.
Inverter cuts off when the battery reaches 85%-90% of its capacity to protect it from deep discharge. So pl consider only 90% of battery capacity.
Each battery has 12v.
Battery capacity ranges 135, 145, 150, 200 ah.
Multiply 15v with battery capacity gives you Power available.
Battery Technologies:
Short Tubular (ST)- Lower Capacity (AH). General life is low compared to Tall Tubular Batteries hence carries lesser warranty. Low in price
Tall Tubular(TT) - Higher AH, Higher Capacity ( AH ) hence costlier.
