<p class=MsoNormal>Hi Folks......we have an upcoming Sunny Island/Sunny Boy AC
Coupled system installation.....We have mostly done Outback and Xantrex battery
based systems.......and like the available supporting DC load centers with main
breakers and other DC load and charging breakers......<br>
What are folks using for the Sunny Island products? Outback Flexware DC 500's?
or 1000's?<br>
This particular system will consist of 4 Sunny Islands and therefore will need
four main breakers...... We primarily need a breaker box to locate our
main DC breakers coming from the battery bank.......Any advice, experiences
would be appreciated......<br>
<br>
Also on that note.....anyone wish to share any experience or advice on the GNB
Absolyte GX series batteries or the East Penn Deka UnigyII as a standby grid
connected back up battery bank....They both seem like they are good for
primarily hanging out in float with occasional deep discharges not negatively
affecting the health of the batteries.....This is the type of service we expect
the batteries will be in primarily......Any recommendations of one brand over
the other.....The vertical stacking seems convenient as far as space is
concerned.....maintenece free......any recommendations on a good supplier on
the west coast? Any other brands i should be looking at in the sealed
battery category for a fairly large Ah battery bank?<br>
100 thanks !<br>
