Hi,
I have a question as to why a Giandel PS-2000QAR 12V inverter would just die, dead, nadda, zilch ? I know its an open ended question, but maybe if I explain it may give clues.
I took the rig out on the road, to a park, I had a 380w projector, 500w sound system, a couple laptops with monitors and a Eurorack sound synth running off it all at once. Was drawing approx 800-900w and approx 7-8.5A for about 25mins, powered all devices one by one, projector then speakers were powered up last. All running off one of the 3 inverter GPOs (which I believe are 10Amp each). Normally if power to inverter goes below certain voltage (or batt power goes off) it makes a piercing noise. In this case it just died 5mins after powering up speakers. Could not turn it on at all, no LED red/green/orange/flashing, even after disconnecting power to it, then using different GPO.
I have attached a page which has all the specs of every component - exclude the CSB GP batteries in diagram - they are not connected.
Took it to an sound electronics mate who tested the 4 permanent fuses and regulators and said they were all ok - but didn't want to spend more 'free of charge' time on it.
Unit is 6mths past warranty. Contacted seller Giandel they said/asked a few things (my responses in brackets).
Please according to my way of trying first,
1. Connect the battery using our standard cable? (Yes)
2. Check your battery is fully charged? (Yes)
3. and the battery is enough 12v? (Yes)
4. Do you have another battery? Please connect another battery and try again. No-load and start the items again. (Yes)
5. Do you see any signs of burnt or damage? (No)
6. Sorry, the circuit board schematic is an internal document and we cannot publish it to the public. (FFS)
7. How many amps does your solar panel charge the battery through the solar controller at 12 p.m. at noon (direct sunlight)? (No panels connected at time)
8. What is the total power of the solar panel in watts? (N/A)
9. Technicians will now think that it is a problem of reduced battery capacity or whether the system is properly built. (Batter is fully charged above 12v)
10. How many years has your battery been used? The tech suspected the battery's capacity was declining even when it was fully charged. (As long as inverter 1.5yrs)
11. Can you please provide us the data, and our engineers will help calculate whether the system construction is reasonable? (Done)
Any advice would be most welcomed and helpful!
Much of the system I ended up with came about from the enlightening discussions in this thread > to-shunt-or-not-to-shunt
