Question 1

What is an inverter and what is its primary function in a solar system?

Accepted Answer

The inverter is the central device considered the "brain" of the solar system. Its primary function is to convert the Direct Current (DC) produced by panels and stored in batteries into Alternating Current (AC) at 220V and 50/60Hz, which is suitable for powering all home appliances safely. Modern inverters we provide (like Deye) also manage smart battery charging, synchronization with generators, and system monitoring via mobile apps, giving you full control over your power.

Question 2

What is the core difference between Hybrid and regular (Off-Grid) inverters?

Accepted Answer

A regular (Off-Grid) inverter is designed to work in isolated islands, taking power from panels to charge batteries and power the home, but it cannot "mix" sources simultaneously. The Hybrid inverter is the newer and smarter generation; it can blend power from panels, batteries, and the public grid (or generator) at the same time to feed loads. This means higher efficiency, fuel/electricity savings, and uninterrupted power continuity, making it the most suitable choice for Yemen's conditions.

Question 3

How do I choose the right inverter capacity for my home (3kW, 5kW, or more)?

Accepted Answer

Choosing size depends on "Peak Load", i.e., the total consumption of appliances running *at the same time*. If you run lights, a fridge, and a TV, 3kW might suffice. But if you plan to run a water pump, heater, or AC, we recommend choosing a 5kW or 8kW inverter to ensure stability. Al-Qatta's team can visit you and calculate loads accurately, but we always recommend choosing a capacity slightly higher than your current need to withstand start-up surges and for any future expansion.

Question 4

Which inverter brands do you recommend and provide in Yemen?

Accepted Answer

In the volatile Yemeni market, quality is paramount. At Al-Qatta Establishment, we are authorized agents for **Deye**, currently considered the global "King of Hybrid Inverters" due to its durability and advancement. We also provide other reliable global brands like **Victron Energy** (Dutch) for professional systems, and **Growatt** and **Voltronic** as excellent economic options. All these brands have proven high efficiency in withstanding operating conditions and overload in Yemen, and we provide them with agent warranty.

Question 5

Can I run an AC on a 5kW inverter?

Accepted Answer

Yes, a 5kW inverter (especially from strong brands like Deye) is easily capable of running a 1-ton or 1.5-ton AC, provided that the solar panel and battery array is sufficient to cover the AC consumption. Modern ACs (Inverter AC) consume less power at startup and continuous operation, making them very compatible with solar energy. Upon our visit, we will calculate the number of batteries and panels required to ensure the AC runs for your desired period without stressing the system.

Question 6

What maintenance is required for the inverter to keep it running?

Accepted Answer

The inverter is a sensitive device requiring a clean, well-ventilated environment. Basic maintenance includes: 1) Cleaning air filters (side meshes) every 3-6 months to prevent dust blockage and overheating. 2) Ensuring cooling fans are working properly. 3) Tightening connections and cables once a year (via a specialist technician) to avoid any looseness that might cause sparks or heat. We offer this periodic maintenance service to our customers to ensure a longer device lifespan.

Question 7

What are inverter prices at Al-Qatta Establishment?

Accepted Answer

Prices vary based on capacity (3, 5, 8, 12 kW) and type (24V or 48V system, hybrid or regular). Investing in an original inverter (like Deye with a 5-year warranty) might cost a bit more initially but saves you thousands later in battery maintenance and generator consumption.
