Enphase DOMINATES the space. I can't see any reason to go another
direction. Reliability and service just continues to improve.
If you are looking to save a few bucks, I think you will get what you pay
for. There isn't enough potential savings in a smaller brand to make it
worthwhile.

That's correct you only need one load controller to commission a sunlight

Strangely enough, I am sitting in the driveway of a sunlight only backup

For you SolarEdge pros...
I have a new client with dual 7.6kW Home Hub inverters and single SolarEdge

I hate to be the bearer of bad news, but this is also the case with IQ8
microinverters. The batteries must be able to sustain the load for up to 6
minutes to allow the microinverters to attempt to charge the battery. If
you have loads that exceed the battery output capacity, it could cause the

That may be the case, but if the load exceeds the total battery plus
microinverter output at the time, the microgrid will still fail. Early in
the morning, having IQ8s won't make much difference versus IQ7s. It might
help at high irradiance levels.
Rather than load control, another strategy might
I don’t want to stray too far off track, but it’s worth discussing how

years.

Hi all,
This is just a PSA in case it helps someone in the future. I was under the
impression that the AC Input LED on the Sol-Ark inverters meant that there
is "good" AC detected by the inverter on the grid terminals and after some
period of delay, something should start happening based on how th
I wrote in another thread about an off-grid quad Sol-Ark system that was
shutting down due to parallel stop when one of the four inverters
experienced a DC PV fault, and how that shutdown is far from ideal. The
same system is down once again, this time due to an AC fault code.
The homeowner starte
I'm pretty sure it was mentioned in another thread that similar faults would not cause Midnite AIO paralleled inverters to fault out. I'm not familiar with their protocol used for paralleling, but if it is true, that would be far superior.At a minimum, I would think Sol-Ark inverters with CANBus co

Hi Wrenches,
I am regretting some HomeGrid Stack'd off-grid installations right now.
There is a major flaw in the way these function in an error state. For
those of you that don't know, these 48V batteries are stacked with a single
BMS on top, covering up to 8 batteries below. Each battery module
might be able to help with.

Hi all,
Is anyone willing to share with me a picture or two of the Powerflo5 in a

with some of the weight supported by the floor, and
I'm looking for a suggestion for a good all-around charger for service
purposes. I would consider a 240V or 120V option. The purpose is primarily
to charge 5kWh lithium batteries.
I would probably just pick up an EG4 Chargeverter, but it is back-ordered.
Something more portable would be nice.

I have been thinking a lot recently about the reasons off-grid systems can
shut down, and working on strategies to prevent these nuisances that
require manual intervention.
Ideally, a BMS should never shut down due to low voltage/SOC because a
properly programmed inverter should reach it's cut off
