Safety boundary (read this first)

This guide is limited to model identification, reading labels, using existing documentation, and collecting evidence for your installer. Do not open equipment covers, touch terminals or conductors, alter communication wiring (CAN/RS485), change DIP switch settings, change protection or battery parameters, or attempt commissioning steps.

The DL5.0C Pro manual includes steps and measurements intended for electrical installation and commissioning (for example using a voltmeter and checking polarity). Those actions are installer-only. If you are not completely sure of the exact inverter model, battery model, or how your system is configured, stop at identification and contact a qualified installer/electrician or the relevant technical support.

Step 1: Identify the exact Dyness battery model (not just “Dyness”)

Start with the battery nameplate/label and any purchase paperwork. Record the full model name exactly as shown (including any suffix such as “Pro”). This matters because similar names can still be incompatible.

• Confirm whether your battery is DL5.0C Pro (the model scope for this guide) or another Dyness low-voltage family.
• Do not assume “DL5.0C” and “DL5.0C Pro” are interchangeable.

Solarboss explicitly notes: the DL5.0C and the DL5.0C Pro are not compatible with each other. If your site has mixed modules, or if you are unsure which version you have, stop here and ask your installer to verify the full battery stack configuration before any compatibility check proceeds.

Step 2: Identify the exact inverter model (Solis or GoodWe)

Next, identify the inverter by exact model code, not by brand. The Dyness compatibility list contains many similar-looking inverter families and variants, and the match must be model-specific.

Homeowner-safe checks you can do:

1. Photo the inverter front and side label (without removing covers). Capture the model number, serial number, and any visible rating plate information.
2. Check your handover pack (installer documentation) for the exact inverter model name.
3. Check your monitoring/app device list if it clearly shows the inverter model (do not change settings).

If you only know “Solis hybrid” or “GoodWe ES” without the full model code, that is not enough to confirm compatibility. Stop and ask your installer to confirm the precise model string.

Step 3: Use the official Dyness low-voltage compatibility list (the only definitive check)

Dyness publishes an official document titled Dyness Low-voltage Battery Compatibility List. It states that the inverters listed below are able to connect to Dyness batteries and provides a brand/model table across Dyness battery families, with an update date.

Use the latest list here (check the update date on the document itself):

• Dyness Low-voltage Battery Compatibility List (last updated 27/10/2025)

How to use it correctly:

1. Find your inverter brand section (Solis or GoodWe).
2. Within that brand, locate the exact inverter model code that matches your label/documentation.
3. Check the column for your Dyness battery family—specifically DL5.0C Pro for this guide—so you are matching the inverter model against the correct battery model column.
4. Keep a screenshot or note of the exact row/series name you matched (to share with your installer).

If your exact inverter model is not listed, or if you cannot confidently find a perfect match (character-for-character), treat it as unconfirmed and escalate.

What the Dyness list shows for Solis and GoodWe (examples you must still verify)

The Dyness compatibility document includes both brands in the general list of inverter brands compatible with Dyness low-voltage batteries, and it also lists many inverter model families. For example, the list includes GOODWE and Solis among brands compatible with Dyness low-voltage batteries. It also shows various GoodWe series strings such as GW3648D/5048D-ES/EM/SBP, GW3K-6K-ES/SBP-20, and GW ET LV 6-20kW in the model table.

Important: these are document examples, not a guarantee for your site. A family name that looks similar to your model may still be different (extra characters, region suffixes, generation differences). Only proceed if the exact model code you have is present and the compatibility mark aligns with DL5.0C Pro in the same row.

Step 4: Watch out for “almost the same model” traps

Compatibility issues often come from small differences that are easy to miss when you search by brand name or shorthand. Before you tell your installer “it’s compatible”, double-check these homeowner-visible items:

• Battery variant: DL5.0C vs DL5.0C Pro (Solarboss warns they are not compatible with each other).
• Exact inverter series string: for GoodWe, similar names can exist across multiple ranges (for example ES, ET LV, EM/SBP strings appear in the Dyness list).
• Region/market suffixes: do not guess; match what is printed on the inverter label and what appears in the Dyness PDF.
• Document date: the Dyness list has a stated “Last updated” date. If your installer is using an older copy, ask them to check the latest manufacturer document.

If any of these are unclear, stop. Compatibility confirmation is only as reliable as the accuracy of the model IDs you start with.

Step 5: Prepare a simple “compatibility evidence pack” for your installer

To keep this homeowner-safe and efficient, gather evidence without touching wiring or settings:

1. Clear photos of the inverter model label and the Dyness battery label (DL5.0C Pro).
2. A copy of (or link to) the Dyness compatibility list you used and the exact line item you believe matches (page/row reference).
3. A note confirming whether your battery stack contains only DL5.0C Pro modules (if unsure, state “unknown”).
4. Your site details: installer name, installation date, and any existing monitoring/app identifiers (read-only).

Solarboss also notes that battery systems must be installed and commissioned by qualified personnel with compatible inverters, protection equipment and the latest manufacturer guidance for the supplied configuration. Your evidence pack helps your installer do that work faster and more accurately.

When to stop and contact support (do not attempt DIY commissioning)

Stop and contact a qualified installer/electrician or support if:

• You cannot find your exact inverter model in the Dyness compatibility list.
• You are not 100% sure whether your battery is DL5.0C Pro or a different model.
• Your system appears to include mixed battery models (for example DL5.0C plus DL5.0C Pro), which Solarboss warns are not compatible with each other.
• You believe a setting, communication protocol, or wiring change is required to “make it work”. Those steps are installer-only.

The compatibility PDF advises that if you have further questions, you should contact Dyness technical support. The document lists the Dyness website and a sales email contact in the header of the PDF.

FAQ (quick homeowner checks)

Is brand-level compatibility enough (e.g., “Solis works with Dyness”)?

No. Dyness publishes a model table; you must match the exact inverter model to the exact battery model column (DL5.0C Pro in this guide). If you cannot do that, treat it as unconfirmed.

Can I change DIP switches or communication settings to make it compatible?

No. The DL5.0C Pro manual discusses DIP switch positioning for specific inverter brands before starting the battery, but changing DIP switches and commissioning behaviour is installer-only. Do not attempt this yourself.

Where can I verify DL5.0C Pro details before purchase?

Solarboss provides a DL5.0C Pro product page with manufacturer-led product data, technical specifications and resource links intended to help customers and installers check important details before purchase.
