Is the Deye 18kW inverter suitable for South African load shedding?

Yes. The inverter automatically switches to battery power during load shedding, helping keep selected circuits powered with minimal interruption.

Which batteries are compatible?

The inverter supports many lithium-ion batteries that communicate through CAN or RS485, as well as lead-acid batteries when correctly configured.

Can I use this inverter without batteries?

Yes. It can operate as a grid-tied solar inverter, although batteries are recommended if you want backup power during outages.

Can this inverter work during load shedding?

Yes. When paired with compatible batteries and correctly installed, it can continue supplying backup power during grid failures.

How many solar panels can I connect?

The number depends on the panel wattage, string configuration and design limits. Your installer should size the PV array according to the inverter's specifications.

Does it support generator input?

Yes. The inverter can integrate with compatible generators to recharge batteries or supply loads when solar production is insufficient.

Can I monitor the inverter remotely?

Yes. The Deye monitoring platform allows you to monitor production, battery status, consumption and system performance remotely.

Is the inverter suitable for off-grid systems?

Yes. It can be configured for fully off-grid or hybrid applications depending on the installation.

Is professional installation recommended?

Yes. Installation should be carried out by a qualified solar installer and comply with South African electrical regulations.

Can I add more batteries later?

Yes. Many compatible battery systems can be expanded, provided the battery manufacturer's requirements are followed.

Is the Deye 18kW inverter good for a large house?

Yes. It is suitable for larger residential properties with higher energy demands, subject to proper system design and load calculations.

Does it work with Eskom and municipal electricity?

Yes. It is designed to operate alongside Eskom or municipal grid power in hybrid installations.

Can I export excess solar power back to the grid?

This depends on your municipality and local regulations. Some municipalities permit grid export with the required approvals and settings.

What size battery works best with this inverter?

The ideal battery capacity depends on your daily energy consumption, backup duration and critical loads. A solar installer can recommend the appropriate battery bank.
