Product Summary

The SC-122420JUD is a solar charge controller configured specifically for LiFePO4 Batteries. This versatile PWM controller is a cost-effective way to protect your batteries by conditioning the output of small solar panel arrays up to 280W (@12V) or 560W (@24V). The handy integrated LCD display lets you know the charging status at a glance.

Product Description

The SC-122420JUD is a solar charge controller configured specifically for LiFePO4 Batteries. This versatile PWM controller is a cost-effective way to protect your batteries by conditioning the output of small solar panel arrays up to 280W (@12V) or 560W (@24V). The handy integrated LCD display lets you know the charging status at a glance.

Although designed to charge LiFePO4 (Lithium Iron Phosphate) batteries, it can be easily adjusted to handle AGM/SLA batteries too. The SC-122420JUD controller accepts solar modules up to 50V (don't forget to temperature compensate!).

Bioenno's proprietary CC/CV (Constant Current/Constant Voltage) circuitry provides a regulated voltage output for charging 12V or 24V LiFePO4 (and AGM/SLA batteries). The solar controller also provides a regulated 12V or 24V output for electrical loads (depending on whether a 12V or 24V battery is used).

Please note that for any solar setup in which you are using a panel in conjunction with a battery and/or a load a solar charge controller is absolutely necessary. DO NOT plug a panel directly into your battery or your load!  

This controller does not boost voltage from the solar panel, but instead will regulate a high panel voltage from 50V downwards.  

DC Barrel Plugs included.

To Charge AGM/SLA Batteries - Override Procedure
To charge AGM batteries, you have to setup an override in the controller as follows:
The solar controller has an override feature to charge LiFePO4, SLA and AGM batteries.  Attach the battery first to the controller, then see below:
1) The 1st screen is the battery voltage also known as the "home" screen.
2) Push the left red button.  The second screen is the float voltage of the solar panel to the battery (13.8VDC).
3) The 3rd screen is the charge voltage of the battery (14.4VDC).
4) The 4th screen is the regulated voltage to the load (12.6VDC)
5) Screen 5 is the cutoff voltage (10.8VDC)
6) Screen 6 is a timer screen that is not implemented
7) Screen 7 is the battery type.  By default "b00"  is for Lithium Iron Phosphate batteries.  To charge SLA/AGM batteries, hold the left button for 6 seconds, and the "b00" display will start flashing, then push the right button to change to "b01".
Screen 2, 3, 4, 5, 6 are hard-coded (hard-programmed) -- there's nothing that you would change on those screens.
