## Frequently Asked Questions

### Is this energy meter compatible with all Deye inverters?

No. Compatibility depends on your inverter model and firmware version. Please check your inverter specifications or contact us before purchasing.

### Does this meter require CT clamps?

No. This is a **Direct 100A Version**, meaning the supply wiring passes directly through the meter.

### Can it measure solar production?

Its primary function is measuring grid import and export energy. Solar production data is typically measured by the inverter.

### Can I use it without solar panels?

Yes. It can monitor household electricity consumption, although many customers install it alongside Deye hybrid inverter systems.

### Can this meter help reduce load shedding impacts?

Indirectly, yes. When connected to a compatible Deye hybrid inverter, accurate energy monitoring helps the inverter manage battery charging and household loads more efficiently during South African load shedding.

### Does it work with prepaid electricity meters?

Yes. In most installations it can be used alongside municipal or prepaid electricity meters because it measures energy independently. Installation should always be performed by a qualified electrician.

### Can I monitor Eskom electricity usage?

Yes. The meter accurately measures electricity imported from the grid, making it useful for monitoring Eskom or municipal electricity consumption.

### Does this support zero export to the grid?

Yes, when installed with a compatible Deye inverter configured for Zero Export mode.

### Is professional installation recommended?

Yes. This product should be installed by a qualified electrician or registered solar installer familiar with South African electrical regulations.

### Can this be installed inside a DB board?

Yes. It is designed for standard DIN rail mounting inside most distribution boards.

### Is this suitable for South African homes?

Yes. It is commonly used in South African residential solar installations with compatible Deye hybrid inverter systems.

### What is the maximum current rating?

This model supports direct connection up to 100 Amps.

### Can I monitor electricity usage remotely?

When connected to a compatible Deye inverter and monitoring platform, energy data can be viewed remotely.

### Will this work during load shedding?

If connected to a Deye hybrid inverter with battery backup, the system continues monitoring energy while operating from backup power.

### Does this improve inverter efficiency?

The meter itself does not increase efficiency but provides the inverter with accurate energy information that allows better power management.

### Can this be used for municipal compliance?

Many municipalities require zero export capability for grid-connected solar systems. This meter assists compatible Deye systems with export limitation where required.

### Is this an original Deye product?

Yes, this is a genuine Deye energy meter designed for compatible Deye inverter systems.
