What a swap over...we have a muni project where the higher voltage optimizers on the 480v inverter allowed us to minimize conductor sizing. New central inverter would need to support strings that use that size. And then the labor to remove all those optimizers! But we're replacing one of those inve

I understand this. Whereas I can set absorb times and charged return ampsnfor an FM80, my SolArk appears to give generic times based on size of battery bank. Maybe it's a minimal issue but fact that Rolls has identified a concern is noteworthy to me.Thanks.Howard "Scot" AreyOwner, Solar CenTex254-3
Wow, are we in the golden age of inverter/chargers? If it had 200-a.p pass thru it would be near perfect.Begs the question: are stand alone charge controllers becoming a historical artifact?Howard "Scot" AreyOwner, Solar CenTex254-300-1228

Hate to ask but are these long lead like SMA and Fronius have become? If
shortage, is this some sign that charge controllers are being overtaken by
hybrid inverters with integrated chargers (like Sol-Ark?).

I have found many of the utilities, especially the cooperatives will undersize transformers relative to main service capacity.Wel always try to check and very infrequently is the transformer smaller than proposed system design.We have had to upgrade some transformers. Tough pill but hard to argue
on for a single
module.
Was surprised by one manufacturer who advised us to read that bypass diodes
were not an warranty defect even though the module was making half power.
Good luck, look forward to hearing how your case goes.

I agree. I also had a Bolt battery recall and we joked that GM probably got
better priority than Solar CenTex for limited battery stock.
Glad you added that important context.

That's interesting if it is the max CT input current. The 15kw comes with the 320amp cts so if I use two 150-amp cts in parallel seems I stay below that current.Howard "Scot" AreyOwner, Solar CenTex254-300-1228

I think you're overstating this a bit. The generator integration feature wasn't the make or break selling point. It was simply a response to customer question of whether this would be possible. Of course the answer was that SE said a solution was forthcoming.I hardly believe that is some illegality

Good morning, Wrenches.
We all discuss the NEC when it comes to ESS but the section in International
Residential Code (IRC) R328 is something to look at carefully.

Fronius has been wonderful and as you say, they are prompt.
More importantly, they have a tech team one can reach quite quickly.

er switch where both
the grid and the backup position are open (still allows PV grid-tied
operations to sell back to grid and partially offset loads during normal
grid ops) but closes the grid connection during grid failures so that the
battery backup provides power (with 2 Radians only).

- If the 4th wire is a neutral (I certainly hope it is), where
might I find the ground electrode conductor (the building is relatively new,
less than 10 years I believe.). FYI, the building is metal.
