Re: [RE-wrenches] Outback Radian Generator Charging

[jay via RE-wrenches]

What I don’t understand is that the inverter was limiting amps while the 
generator was not.  
If the generator wasn’t able to produce the power, then it would have had the 
usual issues which causes the inverter to drop it and then reconnect. 
But that wasn’t happening so it appears the generator is doing fine. 

Its 3% per 1000, and the variables of density altitude are:  temperature, 
humidity, air pressure, elevation.  

I don’t understand why the generator support would allow for higher amps as 
well?

You have had many good suggestions but note you are on border line power,
at 2200 teet your power is down 10% note gen's are 80% of name plate, and
you are asking for 7.2 kW from a Genny that with atmospheric correction is
7.2 kW

Re: [RE-wrenches] Outback Radian Generator Charging: Support mode

[Kirk Herander via RE-wrenches]

Can anyone explain why changing to Support mode on the generator input
boosts battery charging amps?

The Radian manual explanation for Support mode gives no clue about this
"fix". It only states that Support mode will allow batteries to provide
extra power to loads if demand exceeds max. gen programmed input amps.
I also have an offgrid Radian seeming to undercharge from a genny, and I
just changed its input mode to Support to see what happens.

Re: [RE-wrenches] Outback Radian Generator Charging

[Dana Orzel via RE-wrenches]

This may be far fetched but I have encountered good voltage & low amperage =
no amperage from solar arrays that baffled me on T/S on others systems &
ultimately: 

We had voltage & low output amperage to no amperage.

Turns out there was a junction box that had been forgotten about in the
crawl space with never tightened split bolts that were crispy black from
arcing.

There was enough contact for voltage readings & not enough for any amps to
flow.

Double check all connections?

Charger Limit is also set to 30 amps. We tried raising the total AC input limit 
to max and that may have helped increase the chargeby 200-300watts up to 4.8kw 
but thats it. By my math we should be able to see about 6KW+/- of charging 
power. 

We are using Generator input mode I  believe.  We will try switching to Support 
mode and see if that helps.  

By the way batteries are 8- Simpliphi 3.8.

Re: [RE-wrenches] Outback Radian Generator Charging

[William Miller via RE-wrenches]

Amos:



At the risk of stating the obvious:  The batteries have to be ready to
accept maximum charge.  They need to be in good condition and fully
discharged.  Max charge amps will occur only briefly then the charge rate
will start to taper.  Your charging settings need to be correct including
temperature compensation.  Any other charge inputs need to be disabled
during testing, such as solar, wind or hydro.



Check for THD on the generator output.  If the waveform deviates much from
sinusoidal the inherent power will be reduced.  Radians have been known to
instigate high THD rates on generator feeds during charging, especially in
Generator input mode.  Trying the Support mode is good advice.



(We had this case
<https://millersolar.com/MillerSolar/case_studies/25_GFI%20Tripping/GFI_Tripping.html>
a while back.  Recently a random person called to relate he had similar
problems and found our case study.  He installed a capacitor (20mFd?) on
the generator leads and the THD decreased significantly.  I have not tried
this.)

Re: [RE-wrenches] Outback Radian Generator Charging

[integrityenergy101 via RE-wrenches]

Charger Limit is also set to 30 amps. We tried raising the total AC input limit 
to max and that may have helped increase the chargeby 200-300watts up to 4.8kw 
but thats it. By my math we should be able to see about 6KW+/- of charging 
power. We are using Generator input mode I  believe.  We will try switching to 
Support mode and see if that helps.  By the way batteries are 8- Simpliphi 3.8.

Hi Amos,

What input mode are you using?

Try switching to "support" mode and see if the charging current increases.

Re: [RE-wrenches] Outback Radian Generator Charging

[Dana Orzel via RE-wrenches]

2200' EL should not influence the generator, seems the first 4500-5000' are
covered like sealevel. How old is gen?

Have you been into the settings menu as well as the Wizard?

I have found settings in one and not the other that definitely effect the
overall parameters.

 

A call to OB might shortcut your Q.

Hello wrenches,

We just installed an GS8048a Radian build with Mate 3SL controller (no Optics). 
 We are having some with charging from the generator, as the generator charging 
seems to be limited to about 4500Watts +/- (20amps AC) when charging through 
the Radian.  It is a Kohler 8.5RES generator and we have the AC input limit set 
to 30amps and the Gen input set to 30amps.  The house load is only about 
200Watts when we are charging.  The system is at 2200ft of elevation, but I 
don’t know if that makes enough of a difference.
The Gen output voltage seems pretty good and holds around 234V-236V while 
charging.

Any thoughts as to why it may be limiting would be appreciated.

Thanks,
Amos

[RE-wrenches] Outback Radian Generator Charging

[Amos Post via RE-wrenches]

Hello wrenches,

We just installed an GS8048a Radian build with Mate 3SL controller (no Optics). 
 We are having some with charging from the generator, as the generator charging 
seems to be limited to about 4500Watts +/- (20amps AC) when charging through 
the Radian.  It is a Kohler 8.5RES generator and we have the AC input limit set 
to 30amps and the Gen input set to 30amps.  The house load is only about 
200Watts when we are charging.  The system is at 2200ft of elevation, but I 
don’t know if that makes enough of a difference.
The Gen output voltage seems pretty good and holds around 234V-236V while 
charging.

Any thoughts as to why it may be limiting would be appreciated.

Thanks,
