⚠️ WARNING: This article is intended for qualified professional electrical installers ONLY. System owners (consumers) should NOT follow these instructions. Improper installation or handling of electrical equipment can result in serious injury, fire, or damage to your system and loss of warranty. If you are a system owner and need assistance, please contact your Emaldo® installer directly. |
Always make sure you have the latest installation manual available.

ALWAYS SWITCH OFF THE SYSTEM WHEN CONNECTING OR DISCONNECTING PV CABLES
It is very important not to oversize each MPPT.
Each MPPT is max 4000W, 14,5A and Voltage Range 90-500Vdc. Max Input Open-circuit Voltage 550Vdc.
Always measure voltage and polarity on each pair.
Mixed PV or oversizing can damage the inverter and the warranty will be void.
Mixing positive (+) and negative (-) cables in a solar system can lead to confusion and dangerous situations.
Here's why it's not a good idea:
Electrical Short Circuits:
In a solar system, positive and negative cables carry electricity in opposite directions.
If you mix them up, there's a risk of creating a short circuit, where electricity flows in unintended paths.
This can cause damage to your system components and pose a fire hazard.
Incorrect Connections:
Mixing up positive and negative cables can result in incorrect connections between your solar panels, inverters, batteries, and other system components.
This can lead to inefficient operation or complete failure of your solar system.
Safety Concerns:
Reversing the polarity (mixing positive and negative cables) can create safety hazards.
It may cause overheating, electrical shocks, or damage to equipment, putting you and your property at risk.
Warranty Issues:
Using cables incorrectly in your solar system could void warranties provided by Emaldo®.
If something goes wrong with your system due to incorrect cable connections, you may not be covered for repairs or replacements.
At our organization, we prioritize the comprehensive logging of all error codes as part of our standard procedure.
This ensures that abnormal behavior, no matter how small, is recorded and analyzed.
By logging all error codes, we create a detailed record of the performance and health of our systems.
This information serves as a valuable resource for our technicians and engineers, allowing them to quickly identify patterns, diagnose issues, and implement effective solutions.
Ultimately, logging all error codes is essential for maintaining the reliability, efficiency, and safety of our operations.
To avoid these problems, always ensure that positive and negative cables are correctly identified and connected according to the installation manual instructions.
Labeling cables and double-checking connections during installation can help prevent mistakes that could compromise the safety and performance of your solar system.
