 ===== Introduction =====
-This can be very useful for DC connected solar energy systems where the VE.Bus SOC is not accurate. The goal is to ignore AC in, unless the battery SOC measured via the BMV falls below 50%. Configure the BMV to close its relay when the SOC falls below 50%. [[https://www.victronenergy.com/battery-monitors/BMV-700#manual|For the BMV 700 read the manual section, 4.2.2 relay settings]]
+This can be very useful for DC connected solar energy systems where the VE.Bus SOC is not accurate. The goal is to ignore AC in (force Inverter mode), unless the battery SOC measured via the BMV falls below 50%. Configure the BMV to close its relay when the SOC falls below 50%. [[https://www.victronenergy.com/battery-monitors/BMV-700#manual|For the BMV 700 read the manual section, 4.2.2 relay settings]]
 Now the BMV will close the relay when the battery SOC is below 50% and this signal can be connected to Aux1 or the temperature input, for example, on the Multi.

-===== Use with HUB2 system without Hub2 assistant  =====
+===== Related info  =====
-For those people who do not want to use Hub 2 assistants (AC out connected solar energy) they can use the above three assistants, plus at the bottom position assistant "Inverter support". By doing this you will have also AC connected solar taken care of and still be using your BMV SOC as the deciding factor to accept grid energy or not. This will also work well in case there is AC connected solar and DC connected solar energy.
+==== 1. Using ESS instead of above ====
+For many applications, ESS will be a better solution than above explained configuration.

+==== 2. Adding the PV Inverter Assistant ====
+For those people who do not want to use the ESS Assistant, but want to add AC-Coupled PV on the output of the Multi, they can use the above three assistants, plus at the bottom position add the "PV Inverter support" Assistant. By doing this you will have also AC connected solar taken care of and still be using your BMV SOC as the deciding factor to accept grid energy or not. This will also work well in case there is AC connected solar and DC connected solar energy.
