Ssolar8484 replied to the thread Solar for poor people?.I doubt the program requires rooftop solar on single family homes to qualify. Community solar in low income area could work. Kind of...

Srooftop solar makes great sense, if the price were about $1/w like it is in the rest of the world

Like.
Well I did more testing today. Based on prior testing I adjusted the load shedding so that string 1 sheds at 92% SOC and reattaches at... -
Ssolar8484 replied to the thread IQ envoy need to be on the same panel as solar input?.It's one of the common problems reported in the Enphase forum.
-
Ssolar8484 replied to the thread Chinese inverter + charging same time?.That UPower is a rebranded PowerJack which is notorious for vastly overrated power capacity. The noisy waveform is due to poor...

Ssolar8484 replied to the thread IQ envoy need to be on the same panel as solar input?.It's best to connect Envoy in the same panel to avoid current and future potential Enphase comms issues and the expensive filter.

Ssolar8484 replied to the thread Quote feedback please?.In general NEC does not officially specify specific UL standards in the codes. Instead the relevant standards are usually mentioned in...
-
Ssolar8484 replied to the thread Quote feedback please?.UL9540 is required. Make sure the battery sticker clearly show the specific UL compliance. There appear to be battery vendors that...
-
Ssolar8484 replied to the thread Quote feedback please?.Is this an off-grid system? If yes, you can probably pick an off-grid inverter and save money. If no (i.e. on-grid), it would be...

Ssolar8484 replied to the thread LFP "UPS" and Load Shifting.A small off-grid inverter/charger or a power station with internal relay and AC input on a timer should work. I have tested such setup...
-
SIf I could find them, I would. I'll do some testing, when I get time. Actually, there's too much information to correct in this...
-
S@timselectric , you had some measurements that challenged my claims. Can you link those here?
-
Ssolar8484 replied to the thread Building a PV Shedding Controller for AC Coupled Solar.Can you also show the grid codes setting? The freq-watt (and volt-watt, etc.) curtail curve (including the frequency shift limits and...

Some new Information I did some testing today and was able to sort out several issues. About a week ago I changed my settings to use...

Ssolar8484 replied to the thread Building a PV Shedding Controller for AC Coupled Solar.That seems odd. Perhaps there is another overall (i.e. not just for AC coupled charging) setting for max SOC charging limit? Slow ramp...

Ssolar8484 replied to the thread Limitation to AC coupling with EG4 18K, help required....Doubtful unless you have actually tried it.

Ssolar8484 reacted to BKY2003's post in the thread Limitation to AC coupling with EG4 18K, help required... with Haha.
I believe it's because the gen side frequency shifts, And the load side does not.
