Prevent solar panels from shutting down by proper installation of a house battery

Recently there have been multiple news stories about the grid being overloaded in good weather due to the many solar panels that are simultaneously feeding energy back into the system. The PV inverters then automatically shut down and, as a result, your solar energy is completely lost.

However, by installing a home battery you can avoid these losses and the solar energy can still be used to supply consumers and charge the battery. Note that this will only work when the MultiPlus II is installed in series on the grid – in which case the Factor 1.0 rule has to be taken into account; you can read more about this rule here.

If the MultiPlus II is placed in series and the tension on the grid rises, it will automatically be disconnected from the grid. However, the MultiPlus II continues to work, so that you create a micro-grid and the PV inverter will keep functioning as well.

If a battery system is placed in parallel on the grid and the PV inverter is connected to the outlet of the MultiPlus II, this too will continue to work.

This is certainly an important argument when deciding whether to install the battery system in series or in parallel on the grid.
