MPPT solar controller question

The unit on my new folding panels has 6 terminals. The ones labelled "Panels" and "Battery" I comprehend, but what are the two (unused) ones labelled as "Loads" for? The Chinglish instructions are of no use and Google failed me.
Thanks in advance.

Some controllers are able to control a security light via an inbuilt light sensitive relay.

And / or the ability to disconnect the load if the battery voltage is low.

Generally unless the unit is well documented and does specifically what you want, it's best to just connect the load to the battery.

I suggest it is not wise to post e-mail addresses in an open forum. There are web crawlers trawling through the web looking for them.

Most email address collecting software is automated code scouring forums and the like looking for the @ symbol.

To get around this use the word "at" instead of @ and "dot" for the dots.
In this way it appears to be a normal sentence to any scouring code.

Mind you it is not infallible but does afford some protection.

So far I have not had any problems using this method, as I said, so far.

Cheers, Bruce.

I had the same question in thread 96942. Just ignore the load terminals

The load terminals can do different things on different types of controllers. If you had posted the make and model number we may have been able to tell you for sure. They are generally used for supplying the house load when you have them installed in your vehicle. They often have a low battery monitor on them that will protect your battery from being accidentaly over discharged. If you have state of charge (SOC) monitoring in the regulator you must route all your load through there for the SOC monitoring to be calculated.

I agree with bks, if your monitor is mounted on your panel then ignore it. Shifting it into your vehicle where it is beside your battery will give improved performance (any resistance in the charging lead reduces performance.) If you do relocate it then I suggest you route your house load through the load terminals (except for large current items that will overload those terminals.)
