Hard wiring a solar trickle charger

Recommended Posts

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

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."

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

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.
