1) Select ‘Use Timer’ and then select ‘Charge Time - Maximum Charge Power’ and the percentage that the
user wants the battery to reach.
2) Select ‘Discharge Time - Maximum Discharge Power,’ and the maximum depth you allow the battery to
go to. Do not touch any boxes at this point.
3) As you are not exporting any power, tick 'Zero Export'.
4) ‘Zero Export Power’ is a small trickle power that will come from the grid to prevent any export.
5) The ‘Maximum Sell Power’ is, in fact, the maximum power of the inverter.
6.2. ON-GRID WITH UPS
There are two options: you can either use a single inverter or two inverters, depending on how stable you
want the power to be. The simplest form is using a single or multi-inverter system.
Most of the time, the supply is coming directly from the grid. But, when the grid fails, it will automatically
switch over to battery even though there is a very short delay of milliseconds for this switching.
In this application, all the power is provided to the load from the grid. Except, if there is a grid failure. In a
simple form: the 'GRID' is the input 'LOAD' is the output.
IMPORTANT:
Unlike the AC coupled application, your power is limited to the maximum power of the inverter. Ensure
that the inverter rating matches your load.
PROGRAMMING:
The programming is still very simple:
1) Basic Setup: set up your time and date, the company name, and language.
2) Battery Setup: set up your battery type. Ensure that you have communication if you are using a lithium
battery. Also, be sure you click the Grid on the Battery Set Up, and set your Battery Charging Current
according to the type of battery you are using. Generally, if you are using a lithium battery with
communication cables to the BMS, it will be automatically set for you.
