Transport
The shipping fee depends on the size and type of the ordered product. For smaller packages, the home delivery fee is 3,790 HUF, for larger products it is 6,490 HUF. For solar panels, batteries and other large products, the delivery is based on an individual price quote, which our staff will always discuss with you after placing the order.

Huawei MERC-600W-PA0 is a device designed for solar systems and is connected to the panels module by module. Its function is to ensure that each solar panel produces as much energy as possible, even if they do not receive the same amount of light due to shadow, dirt, or different orientation. This makes the system more efficient and the energy production more stable.

However, the MERC series is more than just a traditional optimizer. While the SUN2000-600W-P is primarily designed for power optimization, the MERC-600W-PA0 is a smart module controller that provides full module-level monitoring. This means you can see exactly how each panel is performing and safely shut down a module in the event of a fault.

Another advantage of the device is that it makes the system design more flexible: solar panels can be placed more freely, in different orientations or even in partially shaded areas. This allows better use of the roof surface and up to 30% more capacity to be installed on average. The built-in overheating protection ensures that the module switches off if the temperature rises too high and then automatically restarts when it is safe to operate.

The MERC-600W-PA0 is compatible with several models of the Huawei SUN2000 inverter family, but it is important that it cannot be used with other optimizers within a string (for example, the SUN2000-600W-P model).
