Like I said, I havent heard of battery voltage affecting frequency on any system....I do know the FM 80 very well as well as all the well known quality hardware. It no longer suprises me the faults that pop up in undocumented stuff.
I do see input voltage affecting output voltage, The Magnasine is well known for that. It will take some 10 seconds to settle down when heavily loaded
Would agree. This Hz change is independent of load. Drops to 58.3, holds for several hours, raise back to 60Hz after about 3 hours in float.
Exactly when has Magnum Energy be anything but lackluster or do you mean more lackluster than usual.
I don't have experience with them either way.
So are you saying that the pump is not driven by the Magnasine?
Yes. I thought I made that clear.
Normal daily household use: 6-9kWh (Magnum powered)
Pump use: 4-8kWh/day 2-3 days per week (Sigineer powered)
24kWh battery bank.
Non pumping day:
MS4024PAE drops to 58.3Hz sometime during the absorption phase.
Returns to 60Hz about 7 hours later, 3-4 hours after float.
Pumping day:
Completely separate 6kW Sigineer inverter runs deep well pump at about 4kW draw from battery for 1-2 hours.
The only thing the two inverters have in common is the 24V battery.
Solar (2-2.5kW) usually offsets about 50% of the pump load.
10-20% of battery capacity is consumed during pumping.
Battery voltage remains above 24V during pumping.
Absorption is clearly delayed 1-2 hours.
On these days, the Magnasine doesn't enter the 58.3Hz "mode".
Nothing about it makes sense.
The only feedback Magnum has had so far is to perform a soft reset. No change.
At this point, we're probably looking firmly at a threadjack.
