Tycon Solar’s new TP-SC24-20 solar controllers are 3 stage PWM type temperature compensated battery charging controllers. They have multiple load operating modes which can be set through the “key” button on the controller.
The load output has a soft start feature so it can smoothly and reliably power up high capacitance loads up to 20A. There is a convenient On/Off button to disconnect load power when the unit is operated in the default mode (15).
They have full electronic protections for short circuit, reverse current, overvoltage, overcharge, over-discharge and over-temperature. All protections are auto-recovery.
An automatic battery equalization charge automatically engages once every 30days. The equalization charge helps to balance the batteries in an array and reduce the possibility of battery sulfation. The equalization charge is limited to 1- hour duration to preserve battery life.
A special feature is the 5V 1A USB charging port, so a technician can charge his phone or tablet while on site.
Connections are via 6 screw terminals for wire size up to 10AWG. There are four screw holes(3.5mm) for mounting. The controllers are internally fused for protection, but we recommend always using an external 20A fuse between the controller and the battery. There are four screw holes(3.5mm) for mounting.

FAQs
Frequently Asked Questions
LIT is a battery settings mode. When switching to LIT, the S parameters should be the same as the previous default settings.
When battery voltage falls below 10V the battery BMS disconnects the battery discharge. As soon as there is PV voltage the battery BMS connects the charge and discharge. We recommend the customer set the LOAD Output turnoff at 11V so tha load disconnects before the battery BMS disconnects the discharge.
We recommend that you just leave the parameters set to AGM Lead Acid. This is how the Lithium battery BMS is designed. The AGM Lead Acid settings in the charge controller are compatible with the battery BMS.
You won’t see voltage spikes when connected to the battery (BMS), even if the battery BMS disconnects the discharge. No firmware updates are available or needed to switch from AGM lead acid to lithium.
Having physical access to the TPDIN-WEB3 Monitor and log into it.
Select the MPPT tab
What you need to do now is to make sure the enable Load Toggle is selected
At this point you will toggle the load to off then back to On then uncheck the Enable Toggle Load box.
This makes changes to the firmware in the charge controller so now power down your controller – disconnect solar charging then disconnect the batteries by removing the fuse
Wait 1 minute then reconnect the batteries and verify everything comes back on including your load. If everything is back on then reconnect your solar.
The ground between the V- load output on the MPPT solar controller and the TPDIN-Monitor-WEB3 V- needs to be isolated for the MPPT controller to sense the currents properly.
A TP-DCDC-1224 DCDC converter can be used to isolate the power and solve this issue.
The MPPT charge controllers by default are set for 12V/24V auto detect. Using the keys on the front of the unit go into the settings and set for 24V battery instead of 12/24 auto detect. Save the setting. Power down the unit by disconnecting the solar and then battery. Power up the unit. It should power up in 24V battery mode. Re-connect the solar input.
