I have built a campervan and am keen to avoid propane - preferring to use an induction hob.
But it is giving me some issues.
I have 610w of solar on the roof and use a Victron mppt charger (set to spiral) to charge 2x brand new Leoch 110ah AGM leisure batteries wired in parallel.
I bought a cheap Chinese 2000w(4000w peak) pure sine wave inverter but it alarms and cuts out when the induction hob is pulling 1200w or higher.
So I bought a Renogy 3000w inverter (6000w peak) that is better quality. But I get the same result - alarming and cutting out but at any current draw.
Talking to Renogy they suggest I need more battery power. Talking to the battery supplier they say an additional identical battery wired in parallel will make no difference (I guess they feel their batteries should be able to provide the constant 170A required to drive the induction hob for 30 minutes.
So I am stuck.
Looking at voltages across the shunt - the inverter drops the batteries from 13.79v down to around 12v when loaded at 1600w and the tech specs suggest the inverter should only shut down when it drops to 10.7v
There is a 250A breaker in line that is not tripping.
The cables are heavier than supplied by the inverter manufacturer and should be good for 500A so I can’t see the cabling as being the issue. No cable is over 500mm in length.
The cables linking the batteries are 25mm2 as are the cables feeding the inverter.
So now I am scratching my head
Any thoughts gratefully received.
