FAQ

What should I do if the MPPT voltage/current does not match?

If the MPPT input voltage range is lower than the maximum open-circuit voltage of the PV modules (especially at low temperatures), it may cause equipment damage;

Choose an MPPT controller with an input voltage range that covers the maximum open-circuit voltage of the PV modules at extreme low temperatures, and leave at least 10%-20% voltage margin。

When strings are connected in parallel and there are shading or different orientations, the MPPT may not effectively track the maximum power point of each branch.

Use string-level optimizers or independent MPPT branch designs to ensure each branch independently tracks the maximum power point, reducing the impact of shading or orientation differences

Reverse polarity or poor grounding can cause short circuits or equipment failure.

Wire according to polarity markings during installation, use a grounding resistance tester to ensure reliable grounding, and install anti-reverse connection protection circuits.

Poor ventilation or direct sunlight can affect heat dissipation and lifespan.

Install in a well-ventilated, shaded area (such as an equipment box with ventilation holes) to ensure at least 30cm of space around for heat dissipation.

The inverter’s rated power is not matched with the PV array capacity (such as overload or low load operation), or the input voltage range is not compatible with the component open-circuit voltage (especially at low temperatures).

Choose a suitable model based on the maximum power of the PV array and the open-circuit voltage under extreme temperatures, leaving a 10%-20% power margin.

Reverse polarity or fine wire diameter at the DC/AC terminals, or poor grounding, can lead to reduced efficiency, heating, and even short circuits. 

Wire according to specifications, use cables that meet current requirements, and verify grounding reliability with a grounding resistance tester.

Installing in a confined space can lead to poor heat dissipation, sunlight exposure can accelerate aging, and a humid environment can cause circuit corrosion.  

Choose a well-ventilated, cool and dry location, away from flammable materials, and ensure at least 50cm of space around for heat dissipation.

The inverter and battery voltage/charge-discharge curves are not compatible, leading to overcharging or undervoltage protection.  

Choose an inverter that supports the battery type (such as lithium-ion/lead-acid), and control it in conjunction with the BMS.
