I don't understand - did you cut out your AC adaptor you normally use for charging Cellphones etc.etc. Did you install separate points for them? How about the other inverters on the market, do they have the same problems with parasitic currents? ( btw -a am I the only one who does not get the word "inverter" in English? does it exist in the lingo at all?}.
+Dries Fourie Hi I have take all the 12v powered devices I can (Security DVR, 12 v LED security lighting etc) off my dedicated 220V 'Solar circuit' to reduce the load at night and improve the efficiency. As larger solar inverters (5Kv) are very inefficient (90% inefficient)at the very low current drain end ie: 10w LED lighting. Iv'e used a much smaller (20A) DC to DC converter to supply these 'Parasitic' loads directly from the batteries at 90% efficiency. They don't need cooling fans and don't convert from DC to AC and back to DC. Yes I could run these directly from one battery 12v I hear you say (no converter) but my batteries are in 48v Packs. If you drain only one in a pack even a few mA's it creates an imbalance in the pack and screws the entire pack over time believe you me (even a LED voltage monitor will do this over time). So this may initially seem illogical but the net result is efficiency at the low end, and if you want to shutdown (Standby) the inverter you can still have some auxiliary essential services running almost forever on a set of batteries as a backup without re wiring your house.
PSe advise on the wiring you would recommend on the RCT 5KV inverter
Hi that's very well documented already, I cant add any value to the wiring sorry
