My Luxpower converter does not meet the spec
Installed late 2022 and constantly monitored, the 2x3.2kWh batteries are probably OK. The real problem is the Luxpower Tek converter. Despite claims about its specification, it frequently takes an age to switch the load from either grid to battery or battery to grid. Despite the spec that claims switching is very rapid, I have measured this and it is frequently up to a minute or more!! This means that you will pull mains power instead of battery power and then export battery power to the grid when you switch off - on most occasions. It has shattered my original calculations about pay-back time making the project financially unworkable. Very disappointing. Customer 'service' best left undescribed :-( [I have retained all communications ..... as of September 2024]
