[RE-wrenches] Rapid Shutdown Again?

Greetings fellow wrenches; I know we have beat this many times but I once again have not been able to resolve the contradictory information in 690 in regards to implementing 690.12.  As Rebekah Hren pointed out before, the diagrams shown in Figure 690.1(b) show that the /PV System DC Circuit/

Re: [RE-wrenches] Enphase CTs

Hi William, Our metered Envoys in North America can only be used with the Enphase 200A consumption CTs (CT-200-SPLIT). Many of the off-the-shelf CT options have an embedded burden resistor and output millivolts. Our CTs output milliAmps and we have embedded the burden resistor on the Envoy

Re: [RE-wrenches] DC-DC converter for SQFlex

Wrenches, Thanks, all, for your responses. This recently retired ER Doc customer does have an inverter system (old SW’s, one not so good on the scope). Grid and also two generators, Wanted a DC solution also. I like the Grundfos pumps so far, not their opinion to double the battery bank so

Re: [RE-wrenches] Tapping Parallel Conductors

Thanks for the reply August. I’m working to get in touch with the engineer so we’ll see what they say. I agree balancing the tap on all parallel conductors sounds like it would avoid the possibility of any issue, but I can’t think of what the problem would be if current from the grid were

[RE-wrenches] Enphase CTs

Friends: I am fixin’ to install an Enphase system with the Envoy-S and the AC combiner box. I wish to monitor consumption. It appears to me that Enphase offers only one model of CT which may be a bit large for the space I have. The panel is only 100 Amps and thus has smaller feeder conductor

Re: [RE-wrenches] DC-DC converter for SQFlex

The customer needs education! The SQ should be powered from 240vac and the CU can run a generator input if needed. AC power should be designed so that it never goes away offgrid in my opinion. There should be a water tank that can give time to make repairs. Dave Angelini Offgrid Solar "we go
