Re: Adjustable Voltage Boondocker Converter Question
so, higher voltage pm's still put out their rated current limit, yes? and only at eq voltages, they do not, yes? ... which is a moot issue, yes? and therefore, saying you can't expect full current limit output is a crock of you know what, yes? and expecting folks to pay shipping when randy screws up is unacceptable, yes? and accepting randy's bs excuses is also unacceptable, yes? shall i go on? did anyone here complain about not getting full rated amps while eq'ing? did anyone here say the mis-labelling issue is from errin's end? did anyone here know they would be on the hook for additional shipping if they received the wrong product? ... i think i've made my point.814Views0likes0CommentsRe: Trimetric questions
if that 13.5v is the tri's readout, confirm it with your handheld meter. the boondocker's are not set exactly to 14.6v and 13.6v, but fairly close. mine goes into float (~13.2v) only after about 8.5 hours of continuous charge. yours may do different? and my particular 6v's are full at a resting voltage of at least 12.78v, so yours may be higher, as well. the charts are a general guideline, and not to be taken literally. and by resting, i mean sitting with absolutely no loads for that 1 to 3 or 4 days. which means a proper resting voltage can only truly be done while the bank is out of service. but once you know what it takes to fully charge your bank, you can rely on the amps-at-volts charge parameters... such as say 1.8a at 13.6v.752Views0likes0CommentsRe: Trimetric questions
the two 6's are in series for 12v... pos of batt A to neg of batt B... you take your voltage readings from the remaining pos and neg posts. but you can also check across individual 6v batteries by simply taking a reading across each battery's pos and neg post, and compare. they should be very close, if not the same.753Views0likes0CommentsRe: Trimetric questions
the details for programming the tri are in the installers guide, level 1. since you're using a boondocker converter, set P1 to 13.5v, P2 to 2a, P3 to your bank's ah capacity, and P4 to amps. then do a charge. then set P7 to level 3, and P10 to 85%, and next time you charge, see if the tri says 100% soc and about 0Ah's after a full charge to a little under 2a at 13.6v. if it takes over 100% to get to a full charge, decrease P10 to say 84%,, and vice versa. the boondocker converter has a preset setpoint of 14.6v. this is the point at which, once battery voltage reaches 14.6v, during "bulk" charging, the converter switches to "abs" or "normal" voltage, which is 13.6v. it's working as it should. however, when it drops to 13.6v, amps will drop by about 70% of it's amps rating, and thus increase charge time considerably... like many more hours. my pm4b-45 would drop from 45a to about 19a, for example, and then taper from there, instead of tapering from 45a. if you're running a generator, this is not good. if you're on shore power, it means it will take a long time to reach full charge, and will likely never get the bank's sg (specific gravity) readings up to their potential.752Views0likes0CommentsRe: Adjustable Voltage Boondocker Converter Question

PD iota parallax and wfco didn't give you guys the time of day. Do we have it perfect no but at least we are trying. When we adjust these units with much higher voltages the amps will drop I hope you guys all know this. You guys are taking shots at us when you don't even understand the products your buying. No where in any literature does it say a pmbc comes with a meter or dial. A pmbc is made for bmw. If you just keep saying bad stuff about our product don't buy it. We have 40000 happy customers. If your reading this thread to try to determine what to buy these guys are pointing you in the wrong direction. Call me I'll explain to you what their not. If you are going to continue to just rip our product just don't buy it. To this day I have never got one of these units back. It's easy to come on here and complain and keep the product. It must be doing something right. My personal email and number are at the bottom call me if you want the truth. BTW randy is a great guy and if talked to with respect would help anyone with any issue hmmm, so the pm4b's are a custom model? they run at 14.6 bulk, and 13.6vabs... not high voltage at all, when compared to other brand converters. and there is nothing in any of your outdated, inconsistent, inaccurate, literature that says the unit's current limit will decrease significantly (from 60a to 45a) at bulk voltage. so, now you're just insulting my intelligence... and you've now lost me as a customer, as well. how many of those 40,000 even know what their converter is putting out? my guess is, most of them didn't even know where it was located before having to replace it. i talk to rv'ers all the time, and so far, almost every one of them knows squat about battery charging... how convenient. all i know is i paid for 60a, and ended up with 45... and now i'm expected to pay shipping a third time??? because that's your policy???????????? i think i best leave it at that.814Views0likes0CommentsRe: why don't Solar controller mfg/sellers use honest ratings
Perhaps it's a bit like comparing a cheapowatt ps to a megawatt or meanwell? If there's no current limiting protection, then the OP best take care not to go beyond the unit's duty cycle. In fact, many bench power supplies are rated at peak amps, not continuous duty amps. I think it's the megawatt that says right by its connections that it's duty cycle is ~90% of it's rating. yes, here it is: S-350-12 In the case of solar charge controllers, perhaps all the mfg would have to add to their literature is "peak" after the amp rating, with an asterisk pointing to a side note regarding the nec compliance of 25%.267Views0likes0Comments
