DGI inverter.  I do not have any powerful measurement tools, just that it happened.  Darryl --- On Mon, 11/1/10, Nathan Jones wrote: From: Nathan Jones Subject: Re: [RE-wrenches] Charge Control in AC coupled system To: "RE-wrenches" Date: Monday, November 1, 2010, 3:07 PM Wr

Re: [RE-wrenches] Charge Control in AC coupled system

This is for an on grid system that would AC couple when the grid goes down. Would that still void the warranty? At 11:46 AM 10/29/2010, you wrote: Drake - fyi: you will void the warranty on the Enphase inverters. Andrew Truitt Truitt Renewable Energy Consulting 202 486-7507

Don't forget that you can use a AC load as well for an AC coupled system. jay peltz power On Oct 28, 2010, at 8:25 PM, Kent Osterberg wrote: > Howie, > > In an ac coupled system with Outback inverters you could use a diversion > controller such as a Morningstar Tristar 60 on the dc side. Tha

Re: [RE-wrenches] Charge Control in AC coupled system

Greetings Wrenches, I want to AC couple 8 Enphase M190s to a pair of Outback inverters, stacked in split phase. The use of micro inverters could allow for great method of controlling charge to the batteries. A morning Star Relay Driver could be employed to disconnect one or more inverters at

Re: [RE-wrenches] Charge Control in AC coupled system

Hi Ken, I think I must be not seeing the forest or the trees. Maybe I'm missing something, but what I'm trying to do is get the most I can from the AC coupled array (2.25 kW) while still protecting the batteries. I can use the relays in the inverters or in the FNDC to operate a contactor which s

Re: [RE-wrenches] Charge Control in AC coupled system

Doug, In an ac coupled system with a Sunny Boy connected to the FX inverter's output or to the critical loads panel, a grid connected Outback inverter will work the same as it usually does - it is not affected by the Sunny Boy other than by the rise of the ac feeder voltage. Just be careful t

Re: [RE-wrenches] Charge Control in AC coupled system

Howie, In an ac coupled system with Outback inverters you could use a diversion controller such as a Morningstar Tristar 60 on the dc side. That would allow using an ac coupled system and a nicely controlled finish charge for the batteries too. Since there is already a MX60 to do the finish

Re: [RE-wrenches] Charge Control in AC coupled system

We have done several of these systems with various inverter combinations. We used a voltage activated relay in the stone age to switch inverters between battery banks and the grid before the Trace SW came on scene. This little switch opens and closes a relay based on user adjustable set points.

Re: [RE-wrenches] Charge Control in AC coupled system

Hey Mark, Thanks for the proprietary info! However, I'm wondering what prevents the batteries from getting cooked over a period of time if there are light or no loads in the house and lots of sun. I understand that the relays will divert more and more power as voltage increases, but if there is
