Samrey Merlin 2.5 Kw Battery Charge 24 / 48 Volt

The Samrey Merlin wind turbine battery chargeing  packages include a Merlin wind turbine, a choice of tower, power conditioning unit, diversion controller and dump load.

The packages will be available in 24 and 48VDC to meet end users specification.

The Samrey Merlin wind turbine is currently the largest twind urbine in our product family with a rotor diameter of 3.5m and a maximum power output of over 2.5 kW. 

The Samrey Merlin wind turbine conforms to our design philosophy of which excellent performance at low wind speeds is key.

The wind turbine produces high voltage 3 phase AC output to minimise transmission losses terminating in a Power Conditioning Unit that yields either 24 or 48VDC for connection to a matched Diversion Controller and Dump Load for management of a battery bank.

The wind turbine is mounted on either a 10m Guyed or Free-standing tower.

Why should I buy a Merlin 2.5kW wind turbine and not something much bigger?

The Samrey Merlin has been sized at 2.5kW maximum output for several reasons:
1)  Most of Europe now allows permitted development (read as "no planning approval required") on Wind Turbines that are on towers of 10m or less.  The Samrey Merlin wind turbine has 3.5m diameter rotor that is proportionately balanced with a 10m tower in the hope that the UK will follow Europe with this directive.
2)  To grid connect in the UK the electrical Distribution Network Operator (DNO) by law must accept your turbine connection to the grid if the turbine supply does not exceed 16 amps per phase - which the Samrey Merlin does not and is sized not to.  You simply tell the DNO on the day that you have connected your wind turbine and will be supplying electricity to the grid.  You can still connect larger twind urbines to the grid but the DNO does not have to accept it and may charge you to upgrade the Network in your local area to accept your turbine supply.  You will need to ask the DNO's permission in advance of installing a wind turbine larger than a Merlin.

How much noise do small wind turbines make?

All small wind turbines generate some acoustic emissions as their blades move through the air. However Samrey products are some of the quietest turbines around thanks to the low TSR (tip speed ratio) rotor blades. This means that the blades do not need to move as fast -so are much quieter. Depending on the wind conditions, Samrey products generate a swishing sound that is just audible above the background noise of the wind.

How much wind do Samrey small wind turbines need to operate?

All Samrey small wind turbines are ‘rated’ at just 8m/s (17.8mph) instead of the usual 12m/s rating of other turbines. All of this means that Samrey turbines will capture more energy over a range of different wind speeds that are realistic on most sites. Do not be fooled by lesser turbines that use ‘peak power production’ as a marketing tool. On top of this, all of Samrey's products ‘cut-in’ at a much lower speed, which means that a Samrey wind turbine spends more time generating energy instead of ‘freewheeling’ in low wind speeds.
