-Intelligent solar controller:
The product can automatically manage the working of solar panel and battery in solar system. For protecting the lifespan of your battery, once the voltage of the battery drop below 8V, the solar controller will turn off automatically (LCD will be unavailable at the same time).
-Solar Controller System Connection:
-1.Connect the battery to the charge regulator - plus and minus.
-2.Connect the photovoltaic module to the regulator - plus and minus.
-3. Connect the consumer to the charge regulator - plus and minus. NOTE: The reverse order applies when deinstalling! An improper sequence order can damage the controller!

Fantastic little charge controller for a very reasonable amount of money I would have expected to spend a lot more on a 30 amp lipo charger as well as the other chemistry that are available programming is simple configuration is simple the display is effective and very useful it's a great little unit in my experience never had a problem.

Plug and play. Easy to navigate. Cheap but works. Running 2 solar panels 255w each and doesnt overload . Perfect for lithium. Charges battery as should. As described.

Wired this unit in to a solar panel mounted on my boat. I had the panel wired to a control that fed a lead acid battery and it worked fine. I bought this control for a lithium iron battery. I installed it in the place of the lead acid. This control does not work right out of the box. I have checked the wiring and can find nothing wrong. The unit shows no power and has no display. Waste of money. Should have sent it back, but assumed it would work and threw the box and all away.

Works great! I've had no problems with my controller.Good grief. Many of these bad reviews are clearly people that didn't set it up properly. You absolutely MUST connect it to the battery first!!! That's what automatically sets the controller's battery charging Voltage settings... to either 12V Battery or 24V battery.Two bad things can happen if you incorrectly connect the solar panels FIRST:1) It can damage the controller's circuitry trying to feed it power from the solar panels without a battery present.2) A typical 12V solar panel actually generates about 22 Volts, and the charge controller's job is to drop this voltage down to about 12V via a pulse width modulation scheme. By incorrectly connecting the solar panel FIRST, this controller THINKS that you have a 24 Volt battery... that's just a couple Volts low. Then when you actually connect the 12 Volt battery, it will try to charge it up to 24 Volts.I'll admit the manual could use a rewrite for overall clarity.... but it definitely says CONNECT THE BATTERY FIRST.Another confusing thing that I see is people are getting the NEWER model, but the OLDER manual.The NEWER model can do Lead Acid batteries as well as BOTH types of Lithium:1) Lithium ion - called "3S", 11.1 Volts Nominal, (12.6 Volts Maximum)2) Lithium Iron Phosphate (LiFePO) - called "4S", 12.8 Volts Nominal, (14.6 Volts Maximum).If you are unsure which model they shipped to you and wether or not it can charge Lithium batteries, simply look at the three types of batteries that are programmed into your unit by scrolling through the menu. Find the menu option to change the battery type. You will have three choices: B1, B2, B3.Temporarily select B2 for now, this should be for the "3S" lithium chemistry.Now, scroll through the menu and see if the charging Voltage has been programmed for 12.6 Volts? If battery type B2 shows 14.2 Volts or 14.4 Volts or 14.6 Volts, then you have the OLDER MODEL and your controller is designed for Lead Acid batteries. Double check that you selected B2 battery type. B2 should be the "3S" 11.1 Vnomimal, (12.6 Vmax) type of lithium.After you confirm that B2 battery says 12.6 Volts charging Voltage limit, that tells you that this controller can do lithium batteries. You can now go ahead and repeat the battery selection process to choose LiFePO if you need to. LiFePO is battery type B3. "Standard" Lithium chemistry is battery type B2. Lead Acid is type B1.
