Re: [RE-wrenches] automatic transfer switches

There is the SMA Automatic transfer switch if you go with the SMA battery
inverter and SMA pv inverter, it can be located seperate of the battery and
inverter and will take up to 30 kwhrs. of capacity
Just a thought

[RE-wrenches] automatic transfer switches

2019-11-25 Thread Bill Hennessy 
hi folks--
We're installing a grid-tied, battery backup system on a farm where the service 
entrance is on a pole in the yard. At the single-phase, 240v, service entrance, 
there are two main breaker subpanels--one going to the house and one to the 
barn. The buildings are each about 100 feet away from the pole in opposite 
directions. The PV/battery system is located in the barn. When utility power is 
lost and the battery backup kicks in, we are looking for a way to bypass the 
house subpanel at the pole so it won't backfeed the grid. 

When the grid drops out, we need to tie the backup power coming from the barn 
to the line going to the house. We're thinking an automatic transfer switch 
installed at the pole will do the job, but the transfer switches seem to have 
built in delays to work with starting a generator. The switch does not have to 
be service entrance rated.

It looks like the Asco 300 series has time delay adjustments, but it is pricey 
and has a seven-week lead time. (Thank-you PG)

The battery backup system will switch over in milliseconds and we were hoping 
to find something similar for the transfer operation at the pole.  We're 
looking for something simple--hopefully a basic transfer switch that will 
quickly switch and drop out when grid power is restored.
Would appreciate any thoughts or suggestions.

Re: [RE-wrenches] Enphase

And with all Enphase adapters, don't forget to check for continuity and 
connector seating before assembling. On occasion, we've found opens in the 
adapters.

 Hi Jay,
Ran into the exact situation last install season with Enphase. After a lot of 
back and forth emails with pictures basically showing them I wasn't losing it, 
they finally deduced that they were packaging them wrong. So the package part 
number is correct but the adaptor inside the package is wrong. You'll have to 
dig deep into their engineering staff to clear this one up. I'm sorry but I 
couldn't find any emails on who I ended up dealing with on the issue.

Hi all

I am replacing some old Enphase under the new replacement program. 
This one came with adapters to fit from the module Tyco ends to the 
inverterMC4. 

Except, the other end is Amphonel, not MC4. And the inverters are MC4. 

Is this the normal way from
Enphase or did The customer get something unusual/wrong. 

Thx 

Jay
