Hi guys,

I just updated my H3 and got new features, but don't know exactly the purpose, just wondering around.

BasicParameters2:
GridLostSet - absolutely no idea :)
PVEPSEnable - probably enable PV panels generate for EPS supply

OperationMode:
PerrphasePowerExpansion - probably enable a short duration of override above the nominal limits of the phase in unbalanced mode

if you have further information please correct me if i wrong

edit:
The PerPhase Power Expansion

This function refers to specific settings or power extensions for individual phases, adapted to the requirements of the Czech Republic. These settings are not available or used in other countries, which is likely due to differences in regulations or network standards.

Hey,

GridLostSet - Designed for when the H3 is operating completely off-grid with no grid connection allows you to ignore gridlost errors. Only useful if you're completely off grid with no grid connection. Leave off if you use a grid connection.
PVEPSEnable - Exactly as you say, enables pv generation when the grid connection has been lost. used to power loads and charge batteries during a powercut.

Hey Will, thanks for the carification

Can you describe for me the difference of Unbalances load: "Per Phase" or "Total" phase control?

at my egion the billing is "gross amount" so if I export on two phase 50w/50w and import on the 3rd 100w I'll pay for the import like ~0.1€ and the service provider will pay me like ~0.01€

what is the best setup to avoid phase import and maintain the load?
