Ron,You didn’t say whether the 4448 is a PAE or the original AE; at 4,400 rated watts, I’m assuming that it’s a PAE, meaning split-phase 240. Your 2,000W Honda has a 120V output, and I suspect that the 3,800W Champion does too. Have you taken this into consideration?Many years ago, one of the selling points of the early PAE series was that it could charge from a 120V source. I have no idea if this is still true, but it’s worth verifying (along with the AC input connection and any specific charge input settings) before you make that 6-hour trip.

Wrenches Ron
First l would think tech support already asked you this but.
I have seen this with outback,
What is the incoming voltage and freq, the Honda should be fine but the
other hard to say.  Frequency is very important to be right otherwise the
inverter will sit and wait, voltage not as much. Your inverter is a 240 vac
right, are the gennys also?
You might want to make sure its in Gen input not grid input, gen is wider.
With your little gennys it might latch up and disconnect quickly due to
either going out of range.
With gennys always use a pf of .8 and go down from there so a 3 k genny
charging should be around 1200 watts.

Re: [RE-wrenches] Magnum problem

If dc voltage is elevated magnum inverters won’t charge. Force Bulk under the Cntrl menu will test if this is the issue.Rebulk voltage can be adjusted only in you use “silent” final charge rather than “Multi” as final charge state.If using lithium batteries, cc/cv instead of custom battery settings may also be of benefit.RichSent from my iPhoneOn Oct 31, 2023, at 12:11 PM, Starlight via RE-wrenches wrote:Sorry Dan, I meant Ron.

Dan,

Since you are using 120Vac for the source, did you connect to just 1 AC input; 
AC1 or AC2?  You can not parallel same phase to both inputs or damage may 
occur. 

Have you measured the generator frequency and voltage at the inverter input? 
Make sure to reduce the charge rate to 50% or less when supplying 120V only.

Are you referring to the MagWeb when you speak of the "remote monitor"? If
so, then no, it isn't interfering. It is a completely passive device on the
Magnum network and listens only.

[RE-wrenches] Magnum problem

2023-10-31 Thread Ron Young via RE-wrenches

Hello Wrenches,

I am completely stumped. I built a Magnum 4448 panel for a client and it was 
installed by an electrician. It was thoroughly tested before going out the door 
on all functions and pre-programmed for the off-grid site. Electrician just had 
to hang it on the wall and make 4 connections, AC IN, AC OUT, BATTERY, PV. 
Somehow the system wouldn’t go into charge mode. The site is a 3 hour trip each 
way. The electrician was baffled, he had experience installing solar but very 
limited so I went to the site to see what the problem was. After spending a day 
checking out the inverter with two different generators, checking all the 
connections, AC at the inputs at the inverter and at the outputs on the 
breakers, and even removed the cover from the inverter to make sure some 
connections had not shaken loose inside the box on the long bumpy road into the 
property. Everything checked out. So assuming the AC board in the inverter was 
faulty I ordered a new unit to replace and that has now been done. SAME 
PROBLEM! I’m wondering now if it’s possible that the Magnum remote monitor 
could be the problem. It functions properly on every setting but is it possible 
there is an internal fault? Could it prevent the automatic charge cycle from 
initiating? Seems unlikely to me because the inverter can go into charge mode 
even without the monitor. I also tried replacing the connection cable between 
the monitor and inverter but no luck. 

The generators are both small, one a Honda 2kW and the other a Champion 3.8kW. 
Neither is ideal but I have had no issues with these types of generators in the 
past and the client has ordered a larger 10kW unit but we don’t have it yet to 
test. Generators have been run with Eco Mode off. Output to the house on bypass 
is consistent and without problem.

Any suggestions - this is just confounding.

Ron
