PaulF007 Posted March 3, 2017 Share Posted March 3, 2017 So the good news is that I finally got my Eskom prepaid installed on the farm today! It only took 10 months so not bad for Sa! Now that I have the option to go to the grid rather than my genny that runs at R 20 per hour. I would need to change the settings on the inverter. Basicly what I need is that if I go over to the grid the batts should still be charged by the panels but not by the grid.Is this possible? I would imagine that I will keep the inverter on Grid priority and close a relay to put the eskom power to the inverter but I still need to work through that. Speaking of that , what would the max voltage be that you could push through a BMV? I recently got a 25a Geyser relay but the coil takes 220 v to close the contactor. I would assume that the current would be near nothing as it only needs to power the coil. Any ideas? Regards Paul Quote Link to comment Share on other sites More sharing options...
Guest Posted March 3, 2017 Share Posted March 3, 2017 Does anyone know where that thread is where we discussed the BMV relay in depth, where I switch 220v relays with it? Quote Link to comment Share on other sites More sharing options...

Setting 16: OSO. Solar will be the only charge source no matter if utility is available or not. PaulF007 1 Quote Link to comment Share on other sites More sharing options...

Haha we argued this one to death and TTT emerged victor ..... that's why he remembers it . The BMV manual says 60V 1A max. Victron confirmed that the dry contact can actually take 220V AC (and I presume still limited to 1A). I now have a relay that is opened based on BMV SOC. TTT's pearl of wisdom considerably simplified the wiring thereof. I'll have to look for the thread I have been summons for Saturday morning target practice, PaulF007 1 Quote Link to comment Share on other sites More sharing options...
PaulF007 Posted March 4, 2017 Author Share Posted March 4, 2017 Ah thats super news then I can go direct. One ready lot more to go! Quote Link to comment Share on other sites More sharing options...
Mark Posted March 4, 2017 Share Posted March 4, 2017 I needed more than 1A so went to a 10A relay from BMV... don't want to blow my BMV by mistake. Chris Hobson 1 Quote Link to comment Share on other sites More sharing options...
PaulF007 Posted March 4, 2017 Author Share Posted March 4, 2017 Same here so I will get a 0.5a fuse just for incase.. Quote Link to comment Share on other sites More sharing options...
