SOLAR PV – Inverter Options

Inverters

The inverter for your system is a critical component, and as with the solar panels we are happy to install any suitably sized inverter you request.  However to make your life easier the following is our recommended selection of inverters, chosen for reliability, value, warranty, and quality. Please remember that during the lifetime of your solar panels the inverter will probably need to be replaced, so quality and warranty and service levels are critical factors to consider.


 

SMA Sunny Boy

Packed full of innovative technology, the Sunny Boy HF series provides one of the highest yields for transformer-based inverters in this performance class. With its modern graphic display and wireless Bluetooth communication system make the devices highly user-friendly. With unrivalled build quality it is the Rolls Royce of inverters.

It comes with a standard 5 year warranty, that can be extended to a massive 25 years.

Higher financial benefits through maximum yields with an efficiency rating of 96%; one of the highest in it’s class

Up to 1.5% higher energy output due to SMA’s OptiTrac system which enables the inverter to react quickly and accurately to changes in conditions e.g. shading

Clear, user friendly, graphic display providing relevant performance values in an easy to understand format. Bluetooth interface means no unnecessary wiring for a neat and tidy installation.

  • 96% efficiency
  • Highest quality
  • 25 year warranty available
  • German made

 

Solis 2G Inverters

Solis Inverters have been manufacturing Solar Inverters for over 20 years and they have earned the reputation as highest quality value inverter on the market. Solis prides itself on offering world class design and quality, while retaining competitive pricing. The Solis inverters represent a well-respected, value priced brand of inverters and come with a five-year warranty as standard with an optional 10 year upgrade.

The Solis inverters have a maximum efficiency rating of over 97% and features an ultra wide input voltage range, dual MPPT design with precise MPPT algorithm, and controlled inverter technology. Solis inverters are compact and light for easy installation and include numerous protection functions to give the end user peace of mind. We install the units with a WiFi connection to enable you to benefit from Solis’s free monitoring system, and giving the Solis the full functionality of a much more expensive  inverter.

  • 97% efficiency
  • High quality
  • 5 year standard warranty
  • 10 year available

 

Solar Edge HD Wave Optimizing Inverters
The SolarEdge inverters combine a sophisticated, digital control technology and a one stage, efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage, regardless of the number of modules in a string or environmental conditions.

Packed full of patented new features the Solar Edge HD wave inverter is not only the most efficient, but also the one with the longest life expectancy of any inverter on the market, with a 25 year warranty only costing £107.

Inverter Features: • Solar inverters specifically designed to work with power optimisers • Superior efficiency (>99%) • Excellent reliability with standard 12 year warranty (extendable to 25 years) • Built in module-level monitoring receiver • Communication to internet via broadband • IP65 / NEMA 3R – Outdoor and indoor installation.

The inverter combines with Solar Edge Power Optimisers to maximise the power generation of your PV system, by as much as 25%. It has the best  monitoring system and highest future-proofing potential, with its powerful internet connected computer and fully up-gradable systems.

  • 97% efficiency
  • Standard 12 year warranty
  • 25 year warranty available
  • power optimising

 

SolarEdge Panel Optimisers

SolarEdge power optimisers maximise energy from each panel through constant tracking of Maximum Power Point per panel. Optimal efficiency is achieved by automatically maintaining a fixed string voltage and performance can be monitored via the SolarEdge monitoring portal.

Module mismatch occurs when modules in an array do not exhibit fully identical electrical properties or when exposed to different environmental conditions. Module mismatch leads to a different maximum power point (MPP) per module.

Sources of module-mismatch:

  • Partial shading & uneven soiling causes different irradiance levels on different modules
  • Temperature gradient – heat convection across the solar array causes different temperature levels on different modules
  • Manufacturing tolerance & uneven aging rate cause the modules to perform at different MPP parameters

String systems lower the string’s output to the level of the lowest performing module. SolarEdge power optimizers perform MPP tracking for each module individually and therefore extract the maximum energy from each module, regardless of other modules in the string.

  • increase energy yields from your system by up to 25%
  • increase the output from any panel and system
  • reduce the effect of shading
  • 25 year warranty
