The main goal of the ess system is to keep the main meter at 0.
The ess system can provide all you ask for.
Meanwhile , I found out the I will need 3 multiplus-es in my 3-phase house, correct?
additional , I 'd like to know how the multiplus-es decide when to start charging the batteries and when they decide that battery power should be used instead of grid-power? do they just look at the charge level of battery, when battery reaches 90% charged state (SOC) they start the consumption off the battery until DOD drops below 10% or 20%?
thx for your feedback
Is their also a battery-life guard in the inverter, because in winter time our PV system will not produce enough energy to load the batteries , what does the victron offer to prolong the battery life?
