    grid tie relationship in stand alone

    Thanks much for that, can see the logic. Only problem being the current sensor has to be at the inverter and their cables are limited in length. The array we are talking about is from a shed and connecting to circuit at end of house closest shed.

    grid tie relationship in stand alone

    If you ask online about "grid tie in stand alone system" the assumption by search engines is that you want to use a grid tie inverter without a grid (cheat) Which is not what I want to get info on. In a stand alone, panels, battery, inverter, running a house system but no grid going past the...

    BMS shutting off system power when over voltage?

    A couple of amateur comments because having a bit the same issues. Or was. Loose connections! Posted this site about those circuit breakers. Stay away from them. Automotive and not up to the job especially 48 v banks because they dont have high enough voltage rating. I am blaming this CCA crap...

    SunNrg batteries

    a bit of an update and in terms of build quality its gotten even worse. The 100amp circuit breakers are the auto style stuff that I know from experience will not last in this role. I was prepared to replace them but thought they would be ok in short term. Not so, this barrel design has the cable...

    another renogy issue

    The 5000 watt inverter charger that is incorrectly labelled as 3500w model. I saw that on the website and can understand how that might happen. So ordered one. Its the later model to the one Will tested a while ago. Better screen and case earthing. As an inverter it seems to work fine but fails...

    SunNrg batteries

    SunNrg batteries

    Hi, new here but wanting to put out a bit of a warning about these batteries. Bought 2 200ah 48v lifpo4 to replace aging leads in home system. Got them home and failed straight away with one where led didnt show (simple switch on / off volts display). Pulled top off and cell block had moved...
