Bus alternator charging ‘LFP’, initial testing looks promising.

This is a preliminary test for my bus alternator, Lfp charging. The engine is an 1967 Lv 549, 9L gas international harvester engine coupled with: note dbl. pulley and:+1500w heater running. set to idle at: , under load (1500w input) roughly at:.

The alternator was “cool enough to touch” throughout testing. I’ll hook one of these babies to the alternator for more accurate monitoring:

Startup:, 1500w heater, off.

I have one of those bus alternators ready to fit. Just not got around to it. I would be interested to know how you get on

I’m getting along great. Here’s the reason.

I only need 1000 to 1200w to run all of my critical loads, mini split, refrigerator etc. while driving.

The alternator I’m using puts out 100 amps at idle according to the sticker on the side. That’s like 1360w depending on how you do the math.

I’ll never exceed that even at an idle. Which means I’ll likely never burn up my cheap and available $89.00 alternator. And if I do I’ll back down the max charging amps on my Growatt and report back here.

Also I plan to install and use temperature monitoring. I don’t know what’s going to happen when the temperature outside is 120F. I may have to back down the charging amps again.
