Re: [RE-wrenches] SMA SB-41 without WLAN

[Dave Tedeyan via RE-wrenches]

Hi Jeremy,

I've seen that whitepaper from SMA about using the USB to power a Vonets
wifi adapter. It does not work well at all. I tried this and it worked
great for about a week. Then one of the two inverters stopped being able to
power the Vonets at all, and the other Vonets device could not stay
connected to the wifi signal. I called tech support and the person I talked
to said not to use the USB for power and didn't even know that the
whitepaper existed. I had already purchased a few of the vonets devices, so
I tried on another site and had similar bad luck. It connected great at
first, and then a week later stopped working. These were both ground
mounts. The first one, the wifi was coming from a wireless radio at the
house, but that was in front of the array. But the second time, there was a
strong wifi signal coming from behind the array, and it still would not
work. At both sites, I ended up installing an outlet in a box and used
this, which has an ethernet port and ran a cable to the inverters:

Cheers,

Re: [RE-wrenches] Magnum 4024PAE Won't Charge

[Starlight via RE-wrenches]

Hello Drake,

Since the relay board is functioning some times, I would more suspect (1) an 
intermittent controller board or (2) corrosion on the contact area of the 
header connection. They are relatively easy to change and not too expensive. 

One thing I would test first is to unplug the ARC remote the apply AC power. 
The ARC has the ability to control when incoming AC is used. Unplugging it will 
bypass all remote function as a cause, though I highly doubt it is.

Hello Wrenches,

A Magnum 4024 won't charge batteries or transfer loads. The owner of the 
system, now well out of warranty, has spent hours on the phone with tech 
support and even took the unit into a Magnum authorized repair shop. The 
technician declared that it was working perfectly.

On connection to the utility grid, the ME-ARC shows no sign of seeing the 
power. Once in a great while, it will connect and start charging batteries. 
Then it will quit.

This seems to me like a matter of a relay not operating. The technician, who 
checked it out, believes that the problem is with the AC coming in. One tech 
support agent thought the same.

The inverter is 1000' plus from the transformer. The incoming voltage, with 
light loads, is 248 VAC. Shouldn't the ME-ARC at least show that it sees the 
grid, even if the voltage dropped upon connection to the point it couldn't hold 
it?

Isn't the Magnum charger pretty forgiving about voltage input? I've heard they 
can have issues with inverter-generators, but this is 60 Hz grid power.

Thank you,

Drake

Re: [RE-wrenches] outback FM-100

Hi Jay,

Not sure about the Mate3s but I just got shipping notification for Fm100s
from two different vendors. I had given up on them but I think they are out
there now.

Cheers

Re: [RE-wrenches] SMA SB-41 without WLAN

[Mac Lewis via RE-wrenches]

Hey Jeremy,

However, I have had good success with TP Link Nano Router in Client Mode
(as opposed to router, repeat, AP and hotspot mode).  Client mode is great
because it's not re-broadcasting the wireless signal for other devices,
it's basically just acting as an ethernet port.  They seem to be robust and
fairly cheap.   I can't speak to using the USB ports to power them (worth a
try).

Thanks!

[RE-wrenches] SMA SB-41 without WLAN

[Jeremy Rodriguez via RE-wrenches]

Now that there has been some time since the non WLAN units came out, does 
anyone have recommendations for a good WiFi extender to utilize?

Is it OK to use the onboard USB port to power one.   I’ve seen the white paper 
on this set up but have yet to try it.
