Charging battery with Honda 2000

The Meanwell RSP is a Pf corrected machine

Connecting to a generator derived charging source robs current from the generator FIELD The rotor the shaft that spins in the middle. This is like using exhaust gas to jack up a rig. Illogical.

When I soft ramp loaded the Honda with the Meanwell the generator would start on the economy idle setting. Some pricey inverter chargers may or may not have a ramped charger loading circuit. I made my own from discrete components.

Interesting from Mex on how adding the load makes the engine conk out in certain circumstances.

In my case the difference was between a warmed up engine and a cold engine. In his case, with the engine warmed up both times, the difference was in the gasoline having more energy so the engine didn't conk out.

I see that in my case, starting with Eco off to get the engine warmed up faster than at lower revs with it on, may have hidden the Eco on /off comparison for whether the engine would more likely conk out with the same load and gasoline.

Ramping up the load to prevent a stall is an other thing besides IMO. I don't know how the generator is designed for that, but I have seen how my 100 amp charger's amps output ramps up from the low 90s to stabilize at 103 amps on start up. I thought that was the battery acceptance changing as the battery warmed up from receiving a charge, but it might also be something in the charger's design, don't have a clue.

In all cases, the answer to the OP is still that you can't charge the battery faster with Eco off. Faster charging requires higher amps over a shorter time and the inverter circuit breaker will pop at the same limit whether Eco is on or off when you try the higher amps.

Yes

One must take responsibility for including INRUSH into fundamental calculations for proper sizing load to prime mover.

This is what raised my eyebrows...

using UTILITY power, turn on an incandescent light bulb. Then power-up a power supply connected to NOTHING.

Notice the obvious BLINK of the incandescent light bulb. The greater the potential of the power supply the more profound the blink. This will be noted with full utility potential, 12 AWG wiring and a 30 amp circuit breaker. Discounting this would be foolish. Now, direct connect the power supply to a load. Viola! The blink intensifies.

A funny reality with gasoline engines. Even a tiny reduction in RPM causes a major reduction in power. Chain connect the dots and then an enigma presents itself...

A load presents itself so suddenly the reaction time of the economy idle system coupled to the time need to accelerate the engine to handle the load is violated. This is similar to the need to RAMP the load of motor starting. Only show me a system that would modulate inrush to soften it to the point where the load to the generator allows enough time to compensate...

The 3000IU not only stopped, but it also jerked to a halt. Stunned.

Easily avoidable by first defeating the economy mode and allowing generate full-potential to be presented BEFORE connecting it to "overload". Many ship's generators require paralleling a second generator to feed the start-up of a refrigeration system. For around twenty thousand dollars a three=phase soft start could be incorporated. But many refrigeration systems utilize a three compressor staged system. With multiple generators...neat huh?
