Did you have any luck ? It's been 3 years.
I've got the same inverter and I'm plagued with the Premature Float Bug, I guess I'm going to have to buy a Kodac or some other brand that has better firmware. Before I kill the lovely new Hubble AM-4 I just had installed.
Damn Eskom and loadshedding.
Coulomb - You and me both. My fans don't want to switch off after certain amout of battery drain and fully charged again. Have to kill the incomming ac and back on again and fans go off. If the battery drain is less than 25% then the fans work normally. WEIRD
Anyone had any luck getting firmware ? I see the 5kva ones are easily found.
