Technical Questions

Can I use multiple strings with 1 gateway?

Yes, it is possible to use multiple stings with one gateway. In this case, take 1 DC cable of both and route them through the gateway. Please note that you cannot connect 2 strings on 1 MPPT on your inverter. For 2 strings use 2 seperate MPPT connections on your inverter. E.g. string 1 to MPPT 1 and string 2 to MPPT 2.

For more information please check the quick guide which you can download here.

How many modules can I use in 1 system?

The maximum amount (if possible for the inverter) is 50 modules per system at this moment.

What to do in case of poor 4G connectivity?

In case of no or poor 4G connectivity, we advise to use a powerline adapter. With a powerline adapter, you can easily connect the taylor gateway to ethernet via the power grid in the house.

‍

Required materials

2x Devolo Magic 1 LAN
2x ethernet cables

‍

Process

Connect one Devolo Magic 1 LAN to your Internet router using an ethernet cable.
Connect the other Devolo Magic 1 LAN to the gateway using an ethernet cable.
Plug both Devolo Magic 1 LAN adapters into available power sockets within 3 minutes. As soon as the LEDs on both adapters flash white at regular intervals of 0.5 sec., they are ready to operate and automatically start the process of establishing an encrypted connection to each other.
1. Tip: the same wall socket can be used for the gateway and your Internet router can be used by the Devolo Magic 1 LAN, no additional wall socket is needed.
2. If the LEDs on both devolo Magic adapters light up in white, then your devolo Magic network has been set up according to your individual specifications and is protected from unauthorised access.

The Solis mini inverter installed by me is not found, how can I solve this?

It can happen that during onboarding of the system your Solis Mini is not found. See below the steps you can take to fix this issue.

Before starting below procedure, make sure the RS485 cable is connected correctly between the gateway & inverter. See Quick guide here for more information.

If the cable is connected correctly, follow below procedure.

---------------------------------------------------------------------------------------------------------

Important Considerations:

Data Loss: Be aware that a factory reset will erase all custom settings and configurations on the inverter. Ensure you have documented any important settings before proceeding.
Safety: Follow all safety precautions when working with electrical equipment. If unsure, consult a professional.
Model Variations: Different Solis Mini models might have slight variations in the reset procedure. Always refer to your specific user manual for the most accurate instructions.

If you encounter any issues or if the steps differ for your specific model, refer to the Solis inverter user manual or contact Solis customer support for further assistance.

‍

---------------------------------------------------------------------------------------------------------

Follow below steps in the LCD of the Solis Mini Inverter:

‍

Turn off the gateway and AC breaker.
Turn the gateway and AC breaker back on to power up the inverter.
Press 'Enter' to access the main menu.
Navigate to 'Advanced Settings' using the arrow keys.
Enter the password if required (default is often 0010).
Select Restore Defaults, Factory Reset or Restore settings
Confirm the reset when prompted.
Wait for the inverter to reset and restart.
Reconfigure the settings as needed (language, date, time, etc.)

If you encounter any issues or if the steps differ for your specific model, refer to the Solis inverter user manual or contact Solis customer support for further assistance.

How to perform a Scope 12 inspection?

First, you can find the relevant information on the datasheet of the PV panel (see our downloads page).

‍

Performing leakage current test for a scope 12 inspection with a taylor system is performed by:

Short-circuiting the PV panel string with a MC4 Y-plug (Staubli PV-AZB4-EVO 2-UR).
Connecting the measuring device to the PV string through the remaining MC4 male connection. Alos, connect the measuring device to the ground.
The maximum acceptable leakage current is 50 µA when testing with 1000 V.

An overview of the layout is shown in the figure below.

How many panels can I connect in 1 string per MPP tracker on my inverter?

Below table shows information on the amount of panels you can or should use per MPPT on your inverter. Maximum amount of panels is depended on your maximum input voltage of your inverter, minimum amount of panels needed is depended on your minimum MPPT voltage.

Note that:

Below voltages are temperature corrected from Standard Test Conditions (STC). E.g. clouds create a scenario below 1000W/m2, which lowers your total system voltage.
In shadow situations (e.g. chimney close to the panels), take a higher number for minimum amount of panels to make sure your system works optimal.
With a taylor system, only connect 1 string per MPP tracker to your inverter. It is not possible to use 2 strings per MPP tracker.

*all systems and environments are unique, below is a guideline which needs adjustment per case. In case of any doubt contact our support department, we are happy to help.

* The above numbers are based on corrected Standard Test Conditions (STC) values > (STC: 1000W/m2 & 25C)

* For the maximum voltage scenario, the total system voltage is calculated at -15C.

* For the minimum voltage scenario, the total system voltage is calculated at +80C.

Can I "launch" a taylor system in the taylor.installer application when it is dark outside?

When it is dark outside at night, the solar panels will not have power and therefore it will not be possible for the panels to communicate with the gateway. This means that launching the system using the taylor.installer application will not be possible, this can be done the morning after.

‍

When launching a system, make sure to follow below steps in order:

Turn on the inverter
Launch the system in the taylor.installer application on your mobile device
Turn on the Gateway.
