Correct, and I suspect it is not the shape of the wave produced on the up cycle, but the gaps between them that are the trigger for rpm counting As you have both correctly surmized, my next problem is getting a wire to the right place on the alternator I bypassed the marine stores in my search for a high output alt, and laughed at the Balmar prices. I headed striaght down to a farm equipment breakers and found a quality big body alt from a combine. B+ B- D+ terminals only ((( The tach on the yanmar is driven by a sensor above the flywheel removing the old regulator (low side reg) and replaced with Alpha Pro (high side reg) but to get to the diodes and attach a W wire, the case must be split. Not something I want to do I have to remove it again (very difficult job) and take it to an alt shop Then figure out where to attach a lead - hopefully it will be obvious. Those circular rings are the rails for the diodes I assume This is a 6 dipole it seems, so I set that setting in the alpha pro just getting this far has been a lot of work, but it will put out 160a @ 1200rpm all day long at 50-60 deg c

I managed to get upgraded firmware from US tech support today who were actually very helpful I had v1.4, now i have v4.0 The battery oprions now include USER DEFINED and I can access all the fields of the charge profile I do not have epm working, so that is probably why small engine ,ose is not working as you say. I need to remove the alt and figure out a way to solder a wire to one leg of the diodes to get a pulse Your suggestion for a mastershunt is a good one. I will keep an eye out for one Meanwhile I will set the user defined voltages to 13.4, That way I can switch between the internal map for charging and the programmed map with the rotary pot

this is nuts. this regulator needs to able to be switched between charging and maintaining so that the alt can provide power on long motoring journeys. Turning the alt on and off all day would get old very quickly Thank you for the masteradjust v2.2 It also did not have the USER DEFINED field. I now assume it must be the firmware in the Alpha Pro 2 I can find no source for this or even what the current version is

I have made 11 posts and still not able to pm you. Perhaps you could pm me and ill try to respond

victron is good stuff, but it is expensive

I bought one fro0m amazon. A chinese brand. To use it you have to register on their website w personal info and be connected to the internet at all times. They advertised software for it to use w a pc. When I emiald them, they demanded proof of purchase. Never heard back

Thats a very fine Jabsco 23680 pump I use for primary pump on watermaker. does draw some power tho needs think leads and an inline fuse

I have found a 1500w pure sine inverter to run everything I need except the welder and pressure washer. Grinders, vaccuum cleaners, drills and all household stuf inc hairdryer on 1st setting. Good price point too

The main question for me is can you reprogram the BMS cutoff voltages. Some of these settings are too extreeme imo

you are suing a sim card for internet access I assume?

yes I agree on these points I am trying to find another Alpha Pro 2 owner that has had success with either small engine mode, or USER DEFINED settings, let alone real voltages being sensed Even with a current sensing shunt, the charge profile cant adapt as far as I can see. I dont see anything anywhere to suggest this the AP2 can terminate charging based upon a current threshold... but then there are ZERO documents for the software and rudimentary coverage of charging regimens in the AP2 manual or the AP3 manual. Unless Dr, Heide has different information, I deem this unit unfit for any purpose I cant even figure out how to determine if the AP2 software version 1.4 is the latest version of firmware As mentioned, I have a switch to disconnect the lipo pack from the alt (leaving it to charge the LA starter battery) I have never charged the LIPo pack with the alternator. I can watch the current and the voltage of each of the BMS individually to determine when the current drops, but what voltage and current numbers to use? each battery is a 150ah drop in. they pull about 27-30 amps each when charging when that drops to ???? i will disconnect them. Would appreciate the installer for v2.20 ill pm you... small problem, I need 10 posts to pm you

I am not able to buy anything else duy to import duty as mentioned The unit is sold as a stand alone item when in fact it requires a USB adaptor to configure In testing today, the numbers the unit is showing are incorrect The unit reports sense voltage 14.06, meter says 13.46 Battery Voltage 14.09, meter says 13.5 Bulk Config set to 14.25v - software says alt 14.5v small engine mode set to 1000rpm - no change in field current (2.3a to excite aprox 120a) small engine mode set to 4000rpm - no change in field current no idea what alt rpm event is Total run time reporting 2680 minutes (45hrs) - i picked this thing up 6hrs ago and spent most of that time crawling thru the weboshpere

yes well the country I am in has a SEVERE import duty, and it just happened that a local shop had an old Alpha Pro 2 that i got for a great price since the new model is ver is 3. After a lot of research it turns out to be a LOW side regulator, and I have a alt that had a HIGH side regulator, requiring some alt rewiring. The stock charging settings do a failry good job of keeping current around 0.2c but I have never taken the pack to full charge with the alt because I am sure the (UNKNOWN) stock profile is for LA and has 280mins at float voltage - whatever that might be WHAT I AM REALLY LOOKING FOR IS AN OLD VERSION OF MASTERADJUST software. Or perhaps a login code for the new version? I suspect that this latest version has had USER DEFINED battery type removed, and this is what I was counting on to set the charge profile

I have an alternator. Dont hold it against me. I am trying to come up with an automatic way to regulate it such that the LA starter battery can get recharged and not overcharge the LiPo pack when doing long days of motoring. After a GREAT deal of messing about for the last year, I just have a big rotary switch to disconnect the LiPo pack by hand (the LA starter battery is permanently connected to the alt The LiPos are sealed drop in total 600a w internal BMS over bluefluf. Other crimes I confessed at the Lithium crimes tribuneral: guilty of many partial charge / discharge cycles guilty of never reaching full charge in the winter guilty of going to sleep and wking up to find all batteries at 10v cutoff by BMS guilty of using cheep MMPT solar controller "lithium" setting for fully chargin batteries guilty of wakespeed envy guilty of Mastervolt tech stalking guilty of apathy and lithium abuse guilty of scan reading thread AND FALLING ASLEEP https://www.canalworld.net/forums/index.php?/topic/116513-lfp-charge-termination/#comment-2846012 I should be flogged but, instead Im going to drive you nuts with all this

After several months of frustration trying to reach you or anyone in the Netherland and US, where phone calls languish on hold for hours, I would like to bring a few things to your attention My Alpha Pro 2 needs an interface to adjust the settings and came with no temp sensor After scrounging a USB interface and downloading v 2.36 of master adjust (renamed master cant adjust after 4hrs of frustration) I realized that USER DEFINED option is now missing from the battery type drop down! There is also no manual for the software. I have managed to surmise some fields from the Alternator manual, but no info about the meaning of MLI in the battery type drop down - presumably some kind of Li Ion ? Return Voltage - voltage at which charger returns to bulk mode presumably I know you are very smart cos you have Dr thing, and I am just a bumbling peasant, but I would like to know how to terminate the charge WITHOUT more of your expensive frustrating devices for my LiPo4 pack? Thank you Please resign ASAP!
