i think the 8 gauge would be too big for these terminals i used 12 gauge fork terminals they are pretty close together

Get one of the more expensive units. You truely get what you pay for with these things, mine crapped out in about a month.

An inverter will likely exceed the rating of the load output of this controller. However, you could connect the inverter directly to your battery. But the load disconnect feature of the controller will have been bypassed and won't be able to protect the battery from excessive discharge.

The 12 Volts can with the controller, but not the 24 volt, it exceeds the capacity on the charge controller of 12 volts

That is a light indicator for telling you the light you have connected is drawing power

No, you need at least a small battery. The reason for that is because this is set-up to run 12 or 24V systems and the first thing you should do is connect a battery which allows the controller to detect it's power and "auto-adjust" to the correct settings. If you just connect up a solar panel (which may put out ~20V … see more No, you need at least a small battery.

If you just connect up a solar panel (which may put out ~20V but be intended for a 12V system), the controller may detect the ~20V power, auto-adjust to a 24V system and give you 18V+ when you expect ~12V. So it needs that battery to be a signal of what is wanted, without it the settings won't know what to do (and may reset each night when power is lost). Hope that makes sense. see less

Isn't weather proof need a plastic box

That is exactly what the "load" terminals are for, they get shut off when the battery gets to 10.5V or such (so the battery doesn't drain to 0V which OEMs say "just one time draining it to 0V can ruin a battery").

The manual for this controller says "All voltages need to be the virtually the same for all of your system" so if you have solar panels putting out 24V+, then the batteries connected must be ~24V (like the 2 12V in series) and any load on the "load" connection must be 24V. You don't want to connect up a 12V battery an… see more The manual for this controller says "All voltages need to be the virtually the same for all of your system" so if you have solar panels putting out 24V+, then the batteries connected must be ~24V (like the 2 12V in series) and any load on the "load" connection must be 24V. You don't want to connect up a 12V battery and have solar panels putting in ~30V+, the solar panels for 12V should be ~20V or less. If you want to switch between system, then you should disconnect everything and reconnect them in the same order instructed in the manual (first connect batteries allowing it to detect what system you'll have, then connect solar panels & load). I personally would not switch constantly and would just buy another controller for the minimal $10 leaving each one set up for each system. see less

Bought this solar charger controller a couple of years ago to charge the battery of an old car rarely used and parked in a condo carport w/o electric outlet. Was easy to install and works flawlessly with the solar panel. Even after not using the car for a couple of months the battery is perfectly charged and the car starts right away.

I measured 16 mA no load current draw. There is 0.315" spacing for a ring terminal and I was able to use # 8 ring terminals (0.170" ID, 0.330" OD) on the (6) removable screw connectors. The ring terminal's OD needed just a little filing. The screw connector diameter is 0.152" and the square part is 0.292" x 0.292". There is a blue 15 A automotive fuse soldered to the top of the printed circuit board in the front right area on the load output negative trace. The CMP12-10A product works good and was a good price.

It may be too early to write reviews but this review is just based on my initial observation. So far it worked as described without going into technical details. I think the setup is good for an in-expensive regulator. Instructions, clear. I like that it has a battery power indicator (3 LED's). Four star is because at night the LED lights are still on. it doesn't consume much power but still consumes a little even without a load. I have a harbor freight regulator on one of my setup and all the LED's will turn off at night (means no charging from the panel). This is just so inexpensive to pass up and try. After discounts on HF this is still about 9 bucks cheaper. If everything goes well, this will be a good solar car battery maintainer with a minimum of 15W panel. My setup for this is just a regular car battery, a 50W panel laying flat on top of my sunroom, wired with low voltage 12g wire and a 300w inverter (kinda like a UPS). I use some of the stored power just to light up my computer desk using 12v car LED lights. My other setups is another story (like you!-a mad DIY scientist). It did help power my Uverse UPS for modem and phone for an extended internet access, when the power went down.
