<p class=MsoNormal>AC Point of Connection could be to a backfed 20A DP breaker
in the existing GE TM3210CCU load center (100A MB with 100A busbar) if the SMA SB3800
inverter was still available. But a SB4000 requires a 25A breaker which
violates the 120% rule with the existing panel.<o:p></o:p></p>
<p class=MsoNormal>Comments on the options below. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>#1) Go with another 240v grid tie inverter in the 3800W
range, so we can use a 20 Amp breaker. I see PV Powered and Kaco have 3500’s
listed. Any 3.7, or 3.8kW inverters?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>#2) Is it possible to either, change out the Main Breaker in
the above GE load center to a lower amperage MB, or add a Plug In Breaker.
There is a GE “feeder type” breaker # THQL2190 (90 A DP). Could we
use this as the main breaker for the load center above? It is listed as a
10KAIC breaker.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>#3) Swap out existing 32 space load center and replace with
150AML panel with 100A MB kit.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
