22. Simple Battery Sizing Calculation
Battery Capacity (Ah) = Load demand at night (Ah)¹
Maximum Depth of Discharge (%)²
Load demand at night = Total power consumed at night
48V³
(2) The maximum depth of discharge is the percentage of the batteries capacity that can be discharged without causing harm to the life of the battery. The DOD varies from brand and model.
(3) 48V is the battery voltage required by the Hybrid inverter.

23. Simple Battery Sizing Example
If the power used at night is 4kWh, and the depth of discharge is 80%, the battery capacity (Ah) will be …
Load demand at night = 4000/48 = 83
Therefore,
Battery capacity = 83/80% = 104Ah
This means 2 x 50Ah batteries almost provide required power; 3 batteries would be more than enough.

Booting-Up Process
ES system station overview
Once logged in you can see how the system is performing and this slide shows the performance of a system from a few days ago. The check boxes at the top show PV Power, Grid Power, Load power Battery Power and SOC% and each graph can be switch on and off so you can see each individually.

27. Station Report
In this slide I will introduce each performance parameter

28. Condition: PV ON; Peak Generation
Six Work Mode
Mode 1
Condition: PV ON; Peak Generation
Solar generation will firstly support the load, secondly it will charge the battery and finally export to the grid or draw from the grid if the load demands more energy.
The next 6 slides show the behaviour of the system in 6 scenarios. This first slide reflects what was happening in the previous slide where all the PV energy was being used, the battery supported the load and more energy from the grid was required.

29. Six Work Mode
Mode 2
Condition: Grid is off
Solar generation will first support the load connected to back-up side. If more energy is generated, it will be used to charge the battery.

30. Six Work Mode
Mode 3
Condition: No Battery
Solar generation will first support the load, excess power generation will be exported to the grid. If generation level is too low, power will be imported from the grid.

31. Six Work Mode
Mode 4
Condition: Night-time
ES inverter will discharge the battery to support the load. If battery is not enough, the rest of the power will be supplied from the grid.

32. Six Work Mode
Mode 5
Condition: Nighttime, grid is off
ES inverter will discharge the battery to support the load.

33. Condition: Night-time; UPS usage
Six Work Mode
Mode 6
Condition: Night-time; UPS usage
If the customer wants to use the system as UPS, the inverter can also be set to charge the battery by grid.
If you want you can charge the battery from the grid at night to ensure the battery remains charged
