Re: [RE-wrenches] AC Coupling

Hi Jay; I agree, for long outages, a generator is the way to go. It just doesn't make sense to have 5 days of lead acid battery sitting there for years waiting to be used once or twice in an epic ice storm. On the other hand, many places have very unreliable grid power with short outages every

[RE-wrenches] AC Coupling

Wrenches, After Hurricane Irene left a lot of people without power here in the Northeast, customers who have grid-tied systems are asking about some battery backup to power some essential loads. We have used Sunny Islands but they require either 2 Sunny Islands or a step up transformer

Re: [RE-wrenches] AC Coupling

Yes, there should be an uptick in at least inquiries about solar backup here in the NE. I went to a site in CT where I was called in to see why the customer was upset about why her backup batteries went dead when she was told the solar would stay on line and charge them during what is now week

Re: [RE-wrenches] AC Coupling

Hi Larry, Magnum MS PAE inverters do indeed shift the inverter output frequency when the battery is full in order to disconnect grid-tied inverters used in AC coupled systems. It was designed to work in conjunction with a DC diversion load - which is recommended if the system is larger than a

Re: [RE-wrenches] AC Coupling

Brian, Could you speak a bit more to this, please? My understanding is that the need with a string (or, I suppose, micro-) inverter and a battery-based inverter is for a way to disconnect full batteries from being overcharged when the grid is down and sell is disabled.

Re: [RE-wrenches] AC Coupling

HI Larry, I'll chime in here with the other option, ie no batteries at all. Instead its a back up generator. I've found them to be much cheaper, and if you are expecting a longer outage then weather is usually a problem ie its overcast and therefor you'll need a backup for your battery system

Re: [RE-wrenches] AC Coupling

Allan, You're not the only one with your eyes spinning here. Let me clarify a bit as I think you are making it more complicated than it is. There is no need for a manual switch. The GT inverters feed into the sub panel which is being fed by the Magnum. Since the Magnum is fed by the main panel
