![]() Panels of this size usually put out about 36 Vmp. The 180 watt 36 volt panel you have is likely a 24 volt 72 cell panel. The grey and silver Photonic Universe controller at the top of that listing's page is a rebranded Tracer/Epever controller and a much better choice. You could technically over volt it with your 180 watt panel. Notice it has a maximum Voc rating of 42 volts. The controller you have linked to is supposed to be a true MPPT controller but if it is, it's the bottom of the barrel of MPPT controllers and you can do better. If you find a "MPPT" charge controller for 35.99 or some low price like that rest assured it isn't real. Some of the less expensive real ones are Tracer, Epever or HQST. There are a lot of so called MPPT controllers on ebay that are bogus. ![]() Its quit impossible for it to boil a car battery. The solar panel is likely to produce a maximum of about 300 mA. You shouldnt do this with a large solar panel. (you should always connect the battery first) The key here is TRUE MPPT. A 5W solar panel with an open circuit voltage of 18V in bright sun is probably about right for a battery maintainer charger. Generally, to achieve the 12VDC to 120/230VAC system, both PV panels and batteries are. True MPPT controllers will clearly let you know they have a 100 or 150 volt limit The 12/24 designates the battery bank size and these 12/24 models usually are auto adjust by sensing the battery bank voltage. 12V is the most common solar panel wiring connection with batteries. Most of the true MPPT controllers want 36 or more volts to charge even a 12 volt battery. Remember to connect the positive (red) clip first to the positive terminal on the battery, then the negative (black) clip to the. You’ll then use the alligator clips coming out of the output port on the Guardian to connect it to your battery. I don't really want to buy 3 batteries and run a 36v battery set up as my 180w panel won't be able to power it.and I'm hoping I don't have to buy a new panel instead, or spend a few hundred on a suitable charge controller. The Guardian 12V charge controller has an 8mm input so you can connect Goal Zero solar panels to it. between my solar panel and my charge controller? My question is, can I use one of these 12/24v MPPT controllers with a 36v panel? I don't know if the voltage rated on the controller is specifically for the battery? I've been looking at controllers similar to this.įailing that, would it be a sensible thing to use a 36v to 12v Stepdown Module like this one below? There seem to be a lot of 12/24v MPPT controllers out there but I can't seem to find anything of a decent price that can handle 36v input and 12v output. So I've been given a 180w 36v solar panel and I would like to use it with a singular 12v battery. So what may be helpful for you is to utilize a charge controller, rather than connecting the panel directly to the battery itself.
