How is it going with the interaction between you and Sunsynk about their poor service here in South Africa? RE: Horrible experience with Sunsynk support and warranty claim Hi we have a route to remedy this through one of our major suppliers they will do a replacement Swap Out if found that the inverter is infact a warranty failure however the catch is that it is only for people that bought the inverter from our online store and if the inverter was bought from them the other suppliers do not really offer this. We also have given up with Sunsynk Local support when it comes to warranty repairs for products from other suppliers so we have exclusively been selling Sunsynk inverters supplied by the supplier that offers the Swap Out option in the case of a warranty failure. Sunsynk themselves are not very eager to communicate with Us nor with the End User they try to force the Installer to take the brunt of the warranty Issues. We have on many occasions attempted to do so but they are very set in their ways only route according to them is through the Single Sunsynk Support centre in JHB. There may be other suppliers that also offer a swap out option however We are only aware of one the others follow the normal long winded approach. There is still a time factor linked to the swap out option it takes about 2 weeks where waiting for Sunsynk support can take a couple of months. This is also one of the reasons we are slowly moving away from Sunsynk as the go to product and rather supporting Solis which has a Swap out Warranty Policy and a relatively short warranty swap out waiting time their inverters work very very well and the 5 and 6 KW units are Silent I have been testing them for some time now and can confirm that even in 40 degree conditions they do not get very hot nor do they make any sound. As an example I have a client on a Farm in a very rural area that has some problems with his Solis parallel configuration. Solis has Issued him with a replacement inverter they are also paying the installers call out fee to go to his farm and swapp the inverter and resolve the issues onsite without forcing the client to remove his existing system. They have already ascertained that there is a problem and the only way to resolve it is to do the troubleshooting onsite with a replacement unit. The same client had issues with one of the two of his Magneto Wall Mount 5.1 KWH batteries Magneto Energy sent him Replacement batteries before receiving the faulty ones back and they did this in a space of 1 week.. So yes some Manufacturers work with us others think they are too big to be bothered with good after sales service..

February 9, 20242 yr Author Hello all, We are very proud to finally have the ODIN range of Wind Turbines available at our online store. CLICK HERE to see what we have available so far. We have a lot of other wind power products which we will also be adding to the store in the next week. Some are affordable, and some are a little more expensive, however we always strive to provide for every need and requirement. The smaller mechanical pitch control horizontal axis turbines range from 1 to 10 kW, and the larger ones (over 10kW up to 100 kW) use electromechanical and magnetic systems for pitch control of the blades in order to regulate speed of the turbine and sustain constant voltage and power output. Speed control: An issue in wind turbine design One of the biggest issues in wind turbine design is speed control, due to the fact that wind speeds are not constant. A wind turbine that exceeds its rated speed is termed to be in overrun, and can be very dangerous. Hence all turbines on the market try to regulate rotor speeds, all using different methods. For example, some use a method by which the whole head of the turbine pitches up, in combination with a dump load that is built into its controller. These turbines typically peak at wind speeds of 12m/s though, and the production drops sharply down to a fifth of its rated capacity at 20m/s. Other methods used to combat overrun are: · Tail vanes that cause the machines to turn out of the wind; · Dump loads that place maximum electro mechanical load via the generator; and · Mechanical braking systems. In the past, the fixed blade wind turbine models that we sold would be rated 5kW at wind speeds of 8.9m/s, with a rotor speed of 260 rpm, and 6.5kW at 12m/s and 310 rpm. As the rpm increases, so does the production, to a certain point where the speed control kicks in, and then it starts to drop down again, however it would require very high wind speeds to reach those kind of output figures. The problem is that the controller has limitations on maximum output, so we found that the dump loads for these machines were rated at double the rated production at its nominal wind speed. Problems with fixed-blade wind turbines The things that can go wrong with fixed blade turbines are: A burnt-out dump load (they get very hot!) will potentially cause total failure and overrun of the generator, as well as critical damage to the bearings, rotor and windings, and the potential to throw blades; A severed cable between the generator and its controller will cause the same catastrophic damage, because there is no method to slow the rotational speed of the rotor down; Excessive wear and tear on the mechanical components due to erratic production and the turbine moving itself out of the wind continuously. Other negative factors linked to fixed blade turbines are: Difficulties in routing extra power production to devices that can use the extra power when it is available; Micro cycling of the batteries due to DC coupling, with no comms between the controller, battery and the inverter; and Difficult integration with MPPT controllers and integration with hybrid inverter systems. In the past we have been successful in implementing some fixed-turbine models, due to the fact that they come with a well-built MPPT controller, that can handle this kind of power production, however this made them quite expensive. Variable pitch-control horizontal axis wind turbines A variable pitch-control turbine uses the pitch of the blades to alter its speed, similar to the same technology found in aircraft. The advantages of using variable pitch blades vs fixed pitch blades are tremendous. Fixed blade machines do not produce constant rotor speeds, so power production can be very erratic. When rotor speeds are erratic, the mechanical components are more likely to wear out faster, and as a result will require more frequent service, and parts replacement like bearings and slip ring brushes. Advantages of mechanical variable pitch wind turbines The advantages of mechanical variable pitch wind turbines are as follows: Constant rotor speeds can be achieved; Lower mechanical wear and tear, and in turn, lower maintenance costs and longer service life; Almost no risk of a machine overrun due to the mechanical pitch control keeping rotor speeds in check (unless, of course, the pitch control mechanism fails); Much higher average power production, because the machines can produce nominal power from 9 m/s to 25 m/s with an almost flat power curve; Due to the constant voltage and sustained power output, the controllers for the machines do not need to be as robust as that required for turbines with fixed pitch blades, and the controller takes far less of a beating due to it not having to deal with huge power and voltage fluctuations; Higher efficiency, because when we use very high quality MPPT controllers, we can output almost any desired DC Voltage, allowing us to DC couple or AC couple by way of a grid-tied inverter; The advantage of AC coupling means that the turbine will not compete with any other MPPT controllers connected to the battery bank, eliminating micro-cycling completely. It makes the power available in 230/380vAC. This means that the inverter system can dictate what the power is used for, be it to charging batteries or servicing loads; and A lot of other potential efficiencies begin to emerge, such using automation to divert excess power to a usable non-essential load, instead of dumping it to a dump-load. In conclusion, Variable Pitch horizontal axis wind turbines have opened up almost unlimited possibilities to expand our clients’ renewable energy journeys. The only real problem is whether our clients have the required minimum wind speeds available in their area. As a rule of thumb, we recommend a minimum of 6 m/s for it to be viable. If there is anyone interested in wind power, or who wants to learn more about the turbines, how to integrate them with an existing solar system, or who just want to know whether it is viable or not, please do not hesitate to contact me in PM or via email at [email protected] . I would be more than willing to discuss it with you, and to recommend a solution that suits your requirement. We will also soon have engineer-designed and approved towers available for the various different wind turbine models that we have available. Edited February 12, 20242 yr by Powerforum Store
