Description
The Tycon Solarâ„¢ TP-SC24-40N-MPPT solar controllers are MPPT (Maximum Power Point Tracking) temperature compensated battery charging controllers. The battery temperature probe cable is included. The controllers are auto-ranging to accommodate 12V and 24V battery systems. They are designed to charge Flooded, AGM, GEL or Lithium batteries. They also have a USER setting for customizable battery charge settings. They have an integral LCD display that shows Battery Voltage, Battery Capacity, Charging Capacity, Battery Temperature, Load Current and Solar Current.

There is an RS232 interface to connect to the Tycon #TP-SC-BT1 Bluetooth adapter (not included). Using this configuration and the available Android or iOS mobile app, the solar controller can be monitored and controlled from a distance.

FAQs

Frequently Asked Questions

What differences can I expect when switching my batteries to LiFePO4?

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.

Procedure for toggling the LOAD in the Firmware?

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.

My WEB3 is connected to the MPPT solar controller with an RS485 serial cable but the current readings are all zero on the MPPT display and in the WEB3 MPPT page

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.

I have a Tycon MPPT solar charge controller. My batteries are wired for 24V, but they are so low the controller thinks they are 12V batteries and won’t charge them

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.
