Hi, I'm trying to simulation an off-grid project which has 1315KWh annual constant load, 1.42kWp PV generator output and 5 batteries each has capacity at 100Ah. The days of autonomy of the batteries should be over 5 days.

It's proposed to be an off-grid DC coupled system, as PV*SOL cannot simulate it at present so I chosed inverters for it in the software but with no meaning.

The configuration of the system are showed below:

 

When I tried to calculate and get the result something showed as follow:

I've checked that the energy generated per year can cover the power consumption (about 2000 KWh>1315 KWh), how can I get the result of simulation?

Thanks a lot

Hi Wen,

thanks for your question and welcome to the forum community.

There are probably times when the battery is not full enough to cover consumption.

I would recommend working with either load shedding or a backup generator.

Does that help?

Kind regards

Mikio
