Photovoltaic installation - 30.0 kWp with a 100 kWh energy storage

Hello User. we are reviewing your question and we will answer you shortly. Thanks.

Hello, @Michael_123

This kind of scenario it's a little bit complex but it should work normally like this:

 - one Smartlogger 3000A directly connected to a router via ETH cable or 3G/4G SIM card connection (one of them only);

 - one DTSU666-H smart power meter connected on COM port No.2 or 3;

 - 4 x SUN2000-M1 inverters (3x10KTL and 1x5KTL with their LUNA2000-30 batteries) connected on a daisy chain;

Smartlogger is "master" and the "slave" are the inverters, the power meter is conencted directly to the Smartlogger so any export limit or zero export limitation could be implemented normally.

As long the Smartlogger is connected to internet (ETH cable to router or 3G/4G SIM card), it can be connected to FusionSolar server and a single PV plant would host the entire installation.

Basically, this kind of project should be discussed with the solution manager and you should contact an Huawei distributor from your area and to ask them support for this scenario.

Kind regards!

They may be right, it seems that Luna battery is controlled only by the S-Dongle unit and the Smartlogger is useless (at least for the moment).

If the S-Dongle scenario is applicable, you can split the installation in two sepparate systems (A=2x10KTL-M1 with Luna and B= 1x10KTL-M1 +1 x 5KTL-M1, both with Luna batteries), each system would have a Master and a Slave inverter, as in the below picture:

Then, both systems would be connected on the FusionSolar management system under the same PV plant.

This is a scenario which I'm thinking right now but as I already told you, a solution manager would be the right person which would cofirm if my proposed scenario would work normally or not.

Currently, there is no solution for connecting the SmartLogger to LUNA. It may be further developed in the near future. But it takes people and time.

@BetterMing In this figure there is one system: A system (SUN2000-10KTL-M1+LUNA2000, SUN2000-5KTL-M1+LUNA2000 and they are cascaded). To create 30.0 kWp photovoltaic installation with 100 kWh energy storage we have to create two systems A and B (photo below). Those systems will be powered from the same electric line, that's why I am asking about number of power smart meters.

You actually have 4 inverters and you need 2 meters. If inverters of different models or LUNAs are used, a maximum of three inverters can be cascaded in one SDongle. Therefore, the solution described by yourself is feasible. However, you can also connect two SDongles to the same FusionSolar account, or two accounts. You may also build two power stations within one account.
