How do I Choose which System is Right for me? |
| |
All EPL Home Power Systems come complete with Solar Module, Charge Controller, Batteries and DC-AC Inverter. Support frames for ground/ roof mounting and battery racking are available as options.
Choosing a Solar Home Power System Kit
To help you select the right system, you can follow the simple steps below. If you have any questions, please do not hesitate to contact your dealer or EPL. We will be pleased to help. |

| |
Step 1:
List down what type of electrical appliances you would like to power with your solar system (e.g. light) in Column A. Write down the total number of units (e.g. 3 lamps) in Column B. Write down the rated power of the appliance
(e.g. lamp = 11W; radio = 5W) in Column C. If you are unsure of the power rating, check your manual.
Step 2:
Write down the estimated daily running time for each appliance, in this case the lighting (e.g. 3 hrs) in Column D. If you are using a fridge or a freezer, simply write down its daily energy consumption in Column E, e.g. 200Wh.
Step 3:
For each appliance, multiply Columns B, C and D for each line and input the result in Column E (Daily discharge), e.g. the daily energy consumption for
3 light bulbs of 11W each is 3 units x 11W x 3hrs = 66Wh.
Step 4:
Finally, add up the results of Columns E. The total at the end represents your total energy needs for the appliances selected (e.g. 66Wh + 10Wh + 200Wh + 300Wh = 576Wh). |

In this case, choose EPL-300W with daily output of 998Wh |
