New from Myenergi the zappi:
Eco smart EV Charger – Charge your EV with your PV
zappi is a smart EV charger with a difference. Not only does it operate as a traditional EV charger, it can also charge your EV using 100% FREE energy generated from your Solar PV or wind generation.
Here’s the SMART bit. zappi can charge for FREE using your Solar PV during the day and be set to charge at the most economical times at night if you have preferred economy rates from your energy provider. All controllable by the myenergi APP.
No Solar? No Problem!! If you don’t have a PV system, zappi can still operate like an ordinary EV charging station importing from the grid. You can always add your solar system later.
harvi is a clever little device that enablesthe zappi and eddi products to be installed without using a wired current transformer (CT) for measuring the grid and or generation power; instead the CT is connected to harvi. No power source is needed for harvi – the energy from the CT is harvested and used to transmit the measurement signal to the zappi or eddi. This means batteries or electrical wiring are eliminated!
- Remotely control & monitor your myenergi devices
- Access to the latest firmware updates
- Device status LEDs
- Will support time of use tariffs in the near future.
- Comes with an ethernet cable
- Comes with mains power supply
- Required for zappi OLEV approval
Solar Power diverter for free water heating from excess energy from your solar power system
eddi is a solar power diverter for use with grid-tied solar PV or wind turbine systems. Excess energy from the micro-generation system is used to heat water or rooms rather than exporting it to the grid.
There are three main items of a solar PV system:
1 – Mounting Kit
This is the combination of fixings (screws), stainless steel roof hooks / brackets and aluminium rails.
For the majority of applications we use components from a leading German manufacturer K2 with UK based technical and design support and MCS012 Accredited
2 – Panels
These is a staggering range of solar PV panels available on the market these days and little in the way of independent real world data to help. The panels must be MCS accredited:
We select our modules on a combination of the following criteria;
a) Presence of UK / European technical support;
b) Financial strength of the company;
c) Performance in real world independent field trials.
Our default manufacturer is REC, a Norwegian company which runs a vertically integrated operation from the manufacture of silane gas, through solar cell manufacture to module assembly. REC have complete control of each aspect of the manufacturing process.
We are an accredited REC Solar Professional company and as such we receive the support of REC in the unlikely event you experience a module failure. REC will pay us should a solar panel require replacement.
SANYO started the development of amorphous silicon solar cells in 1975 and through constant R & D continued to develop high best products with excellent reliability levels. SANYO became a full subsidiary of the Panasonic Group in 2011 and adopted the Panasonic brand name in 2012.
Panasonics products use a patented technology referred to as Panasonic HIT®. The benefits of these modules are:
- HIT® modules are highly efficient and produce more power per square meter than traditional products. This means that you will need fewer modules on your roof to accomplish very high performance.
- HIT® modules provide many years of reliable operation.
- HIT® modules are based on decades of experience and reference systems worldwide.
In short, where roof space is a limiting factor as it often is in urban areas, high efficiency panels enable more energy to be generated per m2 than products using conventional mono or poly crystalline cells.
3 – Inverters
The inverter is the heart and the brains of the system. It is the single most expensive and complicated component and the one without which your system cannot operate. So it would make sense you might think to choose carefully here. In this area it is particularly important, in our opinion, to select a product from a long established manufacturer with UK based technical support.
We use inverters from one of 3 manufacturers;
SMA, a German company, are the world’s leading manufacturer of grid tied inverters. And let’s face it the Germans do engineering well.
SMA Solar Technology AG is a global leader in the development, production and sales of PV inverters. SMA operates in 19 countries over 4 continents and employs over 5000 staff. SMA have a well established technical support team at their UK offices in Milton Keynes.
Solar Edge go about the business of maximises energy yield from an array in an unusual way. The Solar Edge system uses a voltage optimiser with each modules together with a string inverter. The string inverter just carries out the DC to AC conversion which the optimisers work together to deliver a constant optimal 350V d.c to the inverter.
One of the principle benefits of the Solar Edge approach is that the output of each panel is completely independent from every other panel. In this way, should one panel be partially shaded then the remainder of the array continues to function unimpeded.
Solar Edge systems will generate higher yields in situations where partial shading of the array is expected.
Other benefits include:
- Module level monitoring data (real time and historic)
- 12 year warranty as standard
- Electrically safe system when a.c isolated with just 1v d.c generated per panel.
Power One, now part of the Swiss ABB Power & Automation group, is one of the world’s leading suppliers of inverters to the solar PV market.
With a UK based technical support team in Worthing Power One are well based to support installers in the UK.
The Power One range includes both domestic level single phase inverters as well as three phase commercial and industrial units.
Power One also manufacture micro inverters for small systems and or complicated roof structures.
