Hello everyone,
I’ve tried to understand how the Victron Multiplus II deals with zero injection but I haven’t been able to find a solution to my problem. So here it goes.
In my installation a Huawei inverter collects the production of the solar panels and a Victron Multiplus II inverter stores the overproduction of the panels in batteries and pumps on these batteries when there is no more sun.
Three meters ensure that these equipments don’t operate blindly:
One indicates to the Huawei the grid transit.
Another indicates to the Victron also also the grid transit.
And the last one indicates to the Victron the Huawei’s solar production.
The Huawei has a NO INJECTION mode that works perfectly when I switch off the Victron and use only the solar panels and the Huawei (the domestic consumption is then switched to AC IN).
So I thought that when the Huawei is in NO INJECTION mode, the VICTRON would be seen by the Huawei as part of the domestic consumption needs and therefore it would keep increasing production as long as the Victron needed to charge the batteries.
But, I found that when the Huawei is in NO INJECTION mode, the VICTRON no longer charges the batteries, and the Huawei produces only what is needed for domestic consumption.
So what am I doing wrong? Is there some magic parameter in the Victron to tell it to keep pumping energy to charge the batteries?
Thanks for any help
