| avagadro7@gmail.com: Oct 14 06:47PM -0700 I'm on the road where the problem is so no time to redo the figures. Before installing the system, I went thru the math n have more than correct gauge wireing. There are checks when I am at base....how's the alternator ? what I am asking: suggestions for inherent problems using inverters with alternators in a vehicle system ? as inverter problems specifically ...beyond is the inverter receiving the power it needs for the output we want...yes the inverter has enough feed for the output the inverter does not function with the CTEK charger hella headlamps works best without the inverter on. This was not true last trip. what changed ? |

This was not true last trip. what changed ? You have carefully neglected to tell us the inverter capacity. Still. Overloading an inverter, or running it very close to capacity constantly - especially the bits of junk from China - causes damage to its circuitry. The longer the overload, the more severe the damage. Without load-testing the inverter, you will not be able to verify whether this is true or not in the field other than by its behavior. Clearly, its behavior has changed, so I would start there. Consider as follows: Alternator Rating to Inverter: 15% loss. Inverter Loss: 10% Alternator AC to DC (through the diode block): 5% loss Inverter DC to AC: 10% loss Charger AC to DC: 20% loss. These losses are cumulative: 15% of 200, 10% of 170, 20% of 153, for a net output of 123A (1,476 watts) on good day, downhill with a tailwind. Now, your load: 150 + 400 = 550 550/12 = 46A, without reference to any other loads at the time. And, you wish to charge the batteries as well, I expect? What is the load from the chargers? At least 75 watts, or so. You reference "chargers", so assume 2 at a total of 125 watts, or 10A. I expect your inverter has been toasted, and is now 'toast'. Peter Wieck Melrose Park, PA |
