rossd 16 Posted February 20, 2020 Share Posted February 20, 2020 After buying a Powerteck charger I read it shouldnt be connecting when engine running as alternator might damage it. Are they just being extra cautious or what? wouldnt want it to catch fire or something. Could put in a switch but thats just something else to remember or forget. Power rating 1.5w rated voltage Vmp17.5V Rated current Imp 85.7 mA Open circuit Voltage Voc 21V Short circuit Current Isc 107mA Quote Link to post Share on other sites
Island Time 1,235 Posted February 20, 2020 Share Posted February 20, 2020 Depends, if it has no blocking diodes, it could cause a fire.... Quote Link to post Share on other sites
wheels 543 Posted February 20, 2020 Share Posted February 20, 2020 If you bought it here in NZ, I would take it back and ak for money back. It is not fit for purpose. Quote Link to post Share on other sites
rossd 16 Posted February 20, 2020 Author Share Posted February 20, 2020 IT it says it has blocking diodes Quote: "The Charger will not damage or overcharge your battery. Similarly ,a blocking diode ensures that the charger cannot flatten your battery." Brought from J Car Quote Link to post Share on other sites
wheels 543 Posted February 20, 2020 Share Posted February 20, 2020 What model unit have you got?I took a look at a couple on line, but could see no info regarding Alternator warnings. I find it hard to believe one could not handle an Alternator. Quote Link to post Share on other sites
rossd 16 Posted February 21, 2020 Author Share Posted February 21, 2020 Yes i tend to agree Wheels Powertech Solar Trickle Charger model MB,3504 The warning is: You must disconnect the charger when starting your engine or driving. Electrical surges from the car engine when starting and running may damage your charger Quote Link to post Share on other sites
wheels 543 Posted February 21, 2020 Share Posted February 21, 2020 Arrrrrr, now I see. Nothing at all what I had in my mind.How big is your battery bank? Quote Link to post Share on other sites
rossd 16 Posted February 24, 2020 Author Share Posted February 24, 2020 410 CCA starting and from memory deep cycle 125a/h fla. I haven’t got an auto charge setup but oldfashioned manual switch: off,1,1plus 2,2 type trip. Have 40 watt panel permanently hard wired to a good controller on the house battery. Switch off when not onboard so batteries isolated. Quote Link to post Share on other sites
