Using Batteries to maximise time of use
The system below comprising of Solar Edge Inverter and Reposit control system allows the customer to charges the battery up (LG Chem Resu 10 HV) on Off Peak power 14.577 and then use the battery to power the majority of your loads thru the expensive Peak period.
For example: in the displayed chart it shows that between 1 am and 7 am it charges the battery, however when the tariff rate is expensive (7am-10am) it discharges from the battery
Please note in this example the solar array is switched off for testing purposes. Normally you will also get solar input during sunlight hours.
Maximising battery use and saving you money thanks to Solar Edge / Reposit and LG Chem!
