Frequently Asked Questions

Can a 5.2kW inverter run an air conditioner?

Yes, it can comfortably run a small-to-medium residential air conditioner (typically up to 2500W), but you must manage other heavy loads to ensure the total power draw stays below 5200W.

What does "Can run without battery" mean?

This feature allows the inverter to power your appliances directly from the solar panels during the day, even if you don't have a battery bank connected. This is useful for daytime operations but provides no backup at night.

What is the benefit of parallel capability?

Connecting multiple inverters in parallel allows you to increase your total power output. With three ESENER 5.2kW units, you can achieve a total output of 15.6kW, enough to power a very large home or commercial operation.

What size battery bank is best?

For a 48V system, a minimum of 5kWh (1 x 48V 100Ah) is recommended to match the inverter's power. For optimal performance and longer backup time, a 10kWh (2 x 48V 100Ah) battery bank is ideal.

Is professional installation required?

Yes. To ensure safety, optimal performance, and to validate your warranty, a solar system should always be installed by a certified and experienced technician. This is not a DIY project.

What safety features are included?

The ESENER Pro includes comprehensive protection against overload, short circuits, and deep battery discharge, safeguarding your investment and ensuring reliable operation.

Upgrade to a Smarter, More Powerful System

The ESENER 5.2kW Pro is a top-tier choice for those who need reliable power today and scalability for tomorrow. Its professional-grade features and robust design make it a sound investment. Contact the experts at Sona Solar Zimbabwe to design a complete system tailored to your exact needs.
