Hi,
My gas station ( Petrol / Diesel fuel pump station ) has THREE (3) fuel dispensers. Make Tatsuno, Japan, Each having one 1 HP ( 750 W ) Single Phase, 220V , 50Hz, motor installed in it. Moreover there are eight (8) canopy LED lights of 80W each.
Normal running load if all three dispensers are working ( very very very rare ) is 2,250 Watts. Usually its 1 or maximum 2 dispensers at one time. So for night-time you can assume load to be in range of 640W ( only lights no dispenser working ) to 2140W ( lights + 2 dispensers working).
Here we have lots of power shut downs, usually for 1 hour we have grid electricity, and then for 1 hour no grid electricity. So in 24 hours, there is power available for 12 hours only.
At the moment I have Solar Hybrid Inverter , Make Axpert-MKS from Voltronic, Taiwan, 5KVA ( 4KW ) with a in-built MPPT charge controller of 60Amps. For now I have connected four (4) batteries of 12V, 175Ah each with this inverter, and using it just as a normal UPS, as it has a battery charger in-built too. This current system is able to run my gas station 24 hours a day, without interruption, using Grid elecricity to charge and store power in batteries. For better understanding of my inverter , you can view its specs online at : http://www.voltronicpower.com/oCart2...product_id=132
Please note that customer traffic at night from 1:00am to 6:00am is very low, so almost Zero use of fuel dispensers during this time. During this time just 4 canopy lights are working, but we are open for any customer.
Now I am planning to attach Solar PV Panels to my existing setup. Purpose is to reduce my overall electricity costs. With this installation, I will make Priority Settings in my Inverter to be Solar PV power as my First Priority, and Grid Power as my second priority. With this when there be power shut-down during day-light hours, then instead of just using power from the batteries, they will also be charged either through Solar PV or through Grid. So this way, I feel that I will have less discharge of batteries, and thus extending working life of my batteries, and also will be able to save something on my grid electricity costs.
My estimate is that I should have 2KW to 2.4KW PV Panels.
Please give your comments about my above-mentioned system, as well as my estimated size of 2KW PV Panels..
Thanks.
Omar
