Description

The TS-SC24-40N-MPPT, a 40A MPPT Solar Controller, optimizes your solar power system’s performance. This advanced controller ensures your solar panels operate at their maximum power point, boosting your energy production efficiency. Its robust design and high-quality components guarantee reliable and long-lasting performance.

Firstly, the controller features an intelligent tracking algorithm that continuously monitors and adjusts your solar panels’ operating point. This algorithm maximizes energy harvest from your solar array, even under varying weather conditions. Additionally, the TS-SC24-40N-MPPT includes multiple protection features, such as overcharge, over-discharge, and short-circuit protection, safeguarding your system and extending your batteries’ lifespan.

Moreover, the TS-SC24-40N-MPPT is user-friendly and easy to install. It comes with a clear LCD display that provides real-time information on system performance, including voltage, current, and power output. The intuitive interface allows you to easily configure settings and monitor your solar power system’s status.

Furthermore, this solar controller is compatible with various types of batteries, including lead-acid, lithium-ion, and gel batteries. This versatility makes it an ideal choice for a wide range of solar power applications, from residential to commercial installations.

Key Features:

Auto-Ranging Battery Systems:

Compatible with both 12V and 24V battery systems.

Battery Compatibility:

Additionally, these are suitable for Sealed (AGM), GEL, Flooded, and Lithium batteries. They also offer a USER setting for customizable battery charge settings.

OLED Blue Display:

Display includes PV Volts, Battery Volts/Current/Watts/Temperature, Load Amps/Watts, and charge state. The display dims automatically to save power.

Multiple Load Operating Modes:

  • On/Off Manual Mode
  • PV Voltage Control Mode
  • Dual-Time Control Mode
  • PV + Time Control Mode
  • Note: Load modes can be set through the Mobile or PC app, but not via the front panel. The default mode is On/Off Manual Mode.

Soft Start Feature:

Accordingly, the 20A or 30A load output has a soft start feature to smoothly and reliably power up high capacitance loads. The load can be turned on/off from the front panel or via the PC or Mobile Apps.

Full Electronic Protections:

Include protections for short circuit, reverse current, over-power, over-voltage, over-charge, over-discharge, and over-temperature. The built-in over-discharge protection and low self-consumption ensure the battery is not over-discharged, greatly increasing battery life. All protections are auto-recovery.

Lightning Protection:

Operationally equipped with TVS diode protection against lightning strikes.

Wide Temperature Range:

Operate over a wide industrial temperature range.

Connections and Mounting:

  • Screw Terminals: Connections are via 6 screw terminals for wire size up to 4AWG.
  • Internal and External Fuses: The controllers are internally fused for protection, but it is recommended to use a 63A to 100A external fuse or circuit breaker between the controller and the battery.
  • Mounting Options: There are four 3mm threaded holes for permanent mounting to a flat plate. Brackets are included for mounting to a wall or DIN rail using the Tycon #DIN-CLIPKIT-UNI DIN rail adapter bracket kit.

Parallel Operations:

  • RS485 Interface: The MPPT controllers can be specifically connected via the RS485 interface for parallel operations, allowing multiple solar arrays to feed into a single battery bank.

Applications

  • Remote Power Systems
  • Solar Lighting
  • Solar Power Applications

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.
