OFF-GRID PERFORMANCE
This OFF-Grid Hybrid System is able to cover average energy needs up to 7.20 KWh per day without using Gen or Grid (by estimation).
The average daily energy produced from PV panels is estimated at 10,69 KWh (Winter) up to 25,66 KWh (Summer) in Athens. The stored energy in our battery pack is 12,42 KWh. (80% DOD C20).
The yearly average autonomy of the system is calculated at 1,76 days with an yearly average load loss rate of <2% .
Specifically, the months of November through February, where there may be days when the system will not be able to meet the above needs due to low sunlight and prolonged cloudiness. In this case, you can connect a Generator to cover the loads and at the same time to charge the batteries.
The system has been calculated that it will not be overshadowed by natural or artificial obstacles. If there is shading, there will be a noticeable decrease in system performance and will have to be re-dimensioned according to new data.
SUGGESTIONS
- We recommend installing a gas cooker – LPG oven. (ASK US)
- We recommend installing a closed / open chamber LPG wall heater or solar water heater for hot water use (ASK US)
- It is advisable to avoid the use of air conditioners for heating and to make use of alternative heat sources (gas stoves, wood stoves, pellets).
INSTRUCTIONS FOR GOOD USE OF YOUR OFF-GRID SYSTEM
- We recommend charging and maintaining the batteries at least once a month during periods when the system is powered down to maintain life.
- You do not recommend using higher loads than the rated power of the inverter. Using a higher power load can damage the inverter.
- You do not recommend using higher power loads beyond the time period described above. Using them will result to empty yours batteries earlier and turning the system off until they are charged.
- It is recommended that not all large loads operate simultaneously.
- In case of loss of load due to prolonged cloudiness, it is recommended to limit the consumption to the essentials until the batteries from the PV panels are sufficiently charged.
If we would like to design your own stand-alone system, please contact us and we will provide you with a complete financial offer according to your energy needs
