Solar Inverters & Optimizers

Solar Inverters & Optimizers for hospitality buyers, retailers and home users

Solar Inverters & Optimizers cover a range of products in this category. Solar installers specify inverters per project; commercial property owners size for self-consumption optimisation; homeowners pair with solar panel arrays at install time. The category serves hospitality buyers, retailers and home users who need consistent supply, predictable warranties, and established brand recognition for resale or installation.

Product range and brands

The category covers single-phase and three-phase string inverters, hybrid battery-ready inverters, microinverters, and DC optimisers from manufacturers including SolarEdge, Huawei, Fronius, SMA, Sungrow, Enphase and Growatt. Established consumer and trade brands dominate the category, providing predictable replacement-part availability and manufacturer warranty support that smaller import brands often lack over a multi-year lifespan.

How to choose

Match inverter rating to PV array size: typical DC-to-AC ratio is 1.0 to 1.3. Three-phase inverters required for arrays above approximately 5 kWp in most EU countries. Hybrid inverters add battery readiness without separate hardware purchase later. Match the specification level to the actual use case rather than over-buying. Mid-tier products from established brands typically offer the best balance of cost, durability, and resale support for B2B buyers.

Use cases and buyer segments

Solar installers specify inverters per project; commercial property owners size for self-consumption optimisation; homeowners pair with solar panel arrays at install time. Volume buyers should ask the B2B team for tier pricing and confirmed lead times before placing large orders, especially around seasonal peaks where stock turns quickly.

Frequently asked questions

String inverter or microinverters: which is better?

String inverters are cheaper and simpler for unshaded roofs with consistent panel orientation. Microinverters or DC optimisers excel for shaded sites or mixed-orientation panels. Microinverter installations have higher upfront cost but better long-term yield in non-ideal conditions and easier panel-level monitoring.

How long do inverters last?

Quality string inverters from major brands typically last 10 to 15 years. Microinverters often carry 20 to 25 year warranties matching panel warranties. Plan for one inverter replacement during the typical 25 year solar PV system life span. Inverter cost is around 10 to 15 percent of total system cost.

What is the difference between hybrid and battery-ready?

Hybrid inverters integrate solar PV inversion and battery management in one unit, ready to add a battery later without changing the inverter. Battery-ready inverters can connect to an external battery via a DC link or AC coupling. Hybrid is simpler for new installs; battery-ready provides flexibility for retrofits.

Are DC optimisers worth the cost?

For systems with shading, mixed roof orientations, or panel-level monitoring requirements, yes. SolarEdge, Tigo and similar optimisers add 5 to 10 percent to system cost but recover this in shaded conditions or improved fault detection. For unshaded south-facing roofs, plain string inverters are usually adequate.
