I have both a EU1000 and a EU2000. Both work fine with the Truecharge 40. The EU 1000 revs a bit more when running the Truecharge but it handles it very well. Remember the truecharge rarely outputs 40 amps, it may start there but will drop rapidly as the batterys come up. In general we use the EU1000 when all we want to do is charge batteries and the 2000 if the crew wants the icemaker and blender and microwave for margaritas and nachos while we charge.
Both units have been running down here on board in Mexico
since 2004. I have a 160 amp alternator
on the main engine
, but while at anchor
we hate to run it as the 120 Hp engine
really heats up the salon
Only downside I have found is the truecharge 40 takes a long time to get much back into the battery
bank. I am currently looking at chargers in the 80 to 120 amp range which probably means the EU2000 will not cut it and I will have to put the diesel
gen set back in the boat.
