Since there is a decent amount of “ ANTI-BLUE people present in this thread , you guys may be of some help since I have no experience with any other make than Victron in solar since the spring when I turned it on… have you guys had this happen to your different invert/ chargers ….?
When I started I thought the multiplus 24/3000 was a 3000 watt inverter..then it was explained in the forum it was “3000VA “ and actually a 2400/watt inverter…with some conditions to go 3000 depending on the type loads being used…so over the summer I have pushed it now and then to find it’s limits to learn..
it has done fine running 2000- 2500- 2800 watts as long as needed with a mix of loads , inductive and resistive.. I have taken it to 3300 for a several hours and once to 3600 for about a half an hour With no problems …BUT…
Tonite , I was cooking electric , refer is on electric and a space heater and etc…The RV according to the phone app ( 712 shunt) was drawing about 2700 watts for a half hour.. all everything is cool…im cooking away….
I “accidentally“ turned on the 1000 watt micro wave while already using 2700 watts and punched in 5 min…it came on and was cooking …. a couple of min later I just glanced at the phone app and the wattage was bouncing between 4200 and 4250 watts steady… I thought I messed up..
I started to turn somthing off as I figured the system would shut down….but I didn’t so as to see what would would happen…to see what would fail..
Nothing, except the micro finished its cooking cycle and the app settled back to a steady 2700 watts.. nothing changed ….
no trips, no overload notifications , no nothing…
is this type thing normal .. is that type excess of rating the norm out there for other good quality units.. was it a fluke..? Are good units built with that kind of headroom..?
Can it be counted on to overproduce what I understood it should be able to do.?
It Was about 50 F where the gear and batts were… and the batts were at about 70% SOC .. the voltage took a pretty nice little dip as it was drawing 165-170:amps ..I think that’s about a .40 C rate discharge +/- of the bank.
I don’t see how a 2400 watt inverter can go that high and function just fine for that length of time ..it was not during a surge , it was continuous Cooking…
what am I missing…? Does your units behave similarly..…?
seriously, I gotta be missing somthing..
