Product description

The WeCo 8K0 PRO Master control unit is the main control element of the high-voltage battery system. The system starts with the Master Controller unit, which manages the operation of the first battery cluster and communication with the inverter.

The Master unit is not a standalone battery, but an accessory required for controlling the WeCo 8K0 PRO system. According to the documentation, the system communicates with the inverter via a CAN BUS connection, and a Wi-Fi / Bluetooth antenna accessory can be used for external monitoring.

The control unit plays a role in the coordinated operation of the modules, cluster management, and system monitoring. In the case of multi-cluster systems, the exact configuration is always determined by inverter compatibility and the system design.

How do I choose the right battery?

First, always check if the battery is compatible with your inverter, as not all systems work with all manufacturers. This information is usually found in the inverter's technical data sheet.

Next, you should consider what storage capacity you need (kWh). This depends on how much energy you want to store and which appliances you wish to operate in case of a power outage. If you are considering future expansion, it is advisable to choose a modularly expandable system.

An important distinction is that some systems operate in a closed ecosystem (e.g., only compatible with batteries from their own manufacturer), while other inverters can be connected to products from multiple manufacturers, thus providing greater flexibility.

If you are unsure about your choice, it is worth seeking expert advice – this can help avoid compatibility issues and unnecessary costs.

How do inverter types differ?

Inverters differ in several aspects, depending on the system and requirements for which they are used.

1. Grid-tied (on-grid) inverter
This is the most common type. It feeds the generated energy directly back into the grid and does not operate during a power outage.

2. Hybrid inverter
It is also capable of managing batteries, so the generated energy can be stored. In the event of a power outage, certain systems can also provide backup power.

3. Off-grid inverter
Completely independent of the grid. Used in places where there is no electrical grid (e.g., holiday homes, farmsteads).

4. By phase: single-phase and three-phase

Single-phase: for smaller systems (family homes, lower consumption)
Three-phase: for larger systems, with balanced load distribution

5. String inverter vs. optimized system

String inverter: several panels connected in series
Optimized system: individual optimizers per panel, better performance in case of shading

What happens in a power outage?

In the event of a power outage, the system's operation depends on the inverter type.

If the inverter has a backup (off-grid) function, it automatically switches to battery mode during a power outage, allowing selected consumers (e.g., lighting, refrigerator, essential appliances) to continue operating.

If the inverter does not support this function, the system will shut down in the event of a power outage. This means there will be no power supply even if the solar panels are generating electricity, as grid-tied inverters do not operate without grid voltage for safety reasons.

Therefore, if continuous power supply is important, it is advisable to choose an inverter-battery system that supports backup operation.

What is the warranty on the batteries?

Battery warranties vary by manufacturer and type.

In most cases, a 5–10 year manufacturer's warranty is provided, which for some models may also be tied to a specific number of charging cycles or performance.

The exact warranty conditions are specified for each product, so before purchasing, you can clearly see the duration and conditions under which the warranty is valid.

If you have any questions regarding the warranty, we will help you navigate the details to ensure you choose the system that best suits your needs.

What happens if the battery fails?

As a first step, it's worth checking if the problem is indeed with the device itself, as in many cases, the issue lies with settings, communication, or system connection, rather than the battery.

If the fault is verifiably linked to the product, investigation and resolution will be carried out within the framework of warranty administration, involving the manufacturer or distributor.

If needed, we can assist in initiating and guiding this process to ensure troubleshooting is as quick and smooth as possible.
