I have an off-grid power system.
I use a diesel generator when the sun isn't shining and for battery maintenance.
The generator is 4Kw at 230 VAC
when an 18amp pure resistive load (ie 4 Kw heaters) voltage drops to 220VAC
When the charger is pulling 6 amps the voltage drops to 220VAC
when charger is programmed to pull only 10 amps the voltage drops to 200 VAC
The charger draws a variable current depending on state of charge etc.
I am trying to find out if a circuit is availble to electronically corrrect this.
The current and voltage waveforms are well out of sink.
Normal correction technique is capacitors. However a bank of capacitors and automatic controller to switch different banks in and out is a bit of an overkill for a small system like this.
Does anyone know of any circuits that will fix this problem?
