Dave:
The official answer is that, no, you cannot upgrade a 4 kW to an 8 kW.
There was a hint that there was a non-supported way to do this, but I would
not want to attempt this until after the unit was out of warranty.

Very helpful William! Thank you. I will work with the client to get the load
profile to a point where one 8kW Radian will meet all the household needs, but
it is more likely that 2 Radians will be needed.
Is it possible/practical to parallel a Radian GS8048 with a GS4048? If so, can

William,
I was also surprised to see SMA go down this road (ala Fronius IG). I can’t
speak to why they did this. I’m installing my first 40 series right now.
I have never supported covering the array as a viable method of removing
voltage. It is far safer to unplug the strings on the
Howie:
I have not tried the Wi-Fi capabilities, so I cannot comment on that
aspect. What is relevant, however, is the news I received from a reliable
source that the 40 series inverter will be the last residential inverter
manufactured by SMA that will have an on-board display. As evidence of

Here are the differences between the Outback Radian and FX inverters that I
think are pertinent to your situation:
1.The Radian has generator support. Don’t confuse this with generator
start. Gen support allows the inverter to sync to and aid the generator in

We have used a quad (four wheeled off-road utility vehicle) to pull pumps. We
set up an empty wire spool as a roller right above the well head and attach the
pull rope to the quad. Extra hands manage the poly pipe. Less muscle strain
this way.

I am involved in designing an off grid system that will need multiple
inverters (probably OutBack). My experience over the years has been limited
to no more than 8kW's of inverter on a big system (for me). The load profile
is not completed yet, but it is looking like this may
Dan,
Something else I want to add - since your customer has difficult access for a
service truck, consider if it’s feasible to pull and replace the pump by hand.
I had a 1/2 HP AC pump on almost 200 feet of 1” PVC drop pipe. It took all
strong hands on deck (two decks, if you count down in the
I am looking for comments on the viability of the Wi-Fi option of the new
SB -40 inverters. I noticed some concern here about the poor performance of
this option and am trying to decide whether to use it in the case of a long
distance between the inverters and the router.
I can place a repeater
I have spent hours on the phone with tech support about this issue.
I was a little fuzzy on the reason for all the communications issues,
but it might have been something about there being a windows system
update that was causing it. They have been working on new firmware
for the -40's and the
