Make your secrets open to everybody and you become successful
The wrong concept: People often say: “Keep your idea in secret otherwise somebody else will steal your idea and benefit instead of you.“
Reality: The ideas are copied only after they become successful. 
Some time ago, when starting my business, I had one clever idea of a business plan. I expected to get a lot of money from this plan.  However I spent most of my thinking how to keep the plan secret.  I was fully convinced that if I mentioned just a little bit to somebody, they could easily get the idea and realize the same thing without me. I was also afraid that if some big company boss learns about this idea, they will take their money and realize the same thing in a much larger scale that I myself was able to. 
I learned that such thinking is wrong.  Now I talk to everybody about my projects ideas and visions.  There is nothing to be afraid of. The risk that somebody would take your idea is the same chance as winning a jackpot in a lottery. 
People who are serious about their business, have a lot of things to do, so they most likely have little time and immediate potential to start something new according to your good business idea. 
Also all others, who may wish to take over your smart idea, have the starting position much harder. Because they themselves did not come out with the very idea, they do not know the whole idea and they are somewhat strangers to this idea. 
It seems the best way is to talk openly about your ideas with other people. This way you can get input from different perspectives. As a result you will learn more and you can improve. 
When you keep asking other people what they think about your idea, you can learn many good thoughts and thus avoid some mistakes, especially those other people had made in the past. 
Every mistake costs some money, so those who keep asking and keep receiving good advice to avoid mistake are in fact saving their money.
Do not keep your ideas just to yourself!

Infrared camera can help to analyze a battery problem

Checking the battery pack with an Infrared camera can help to detect a problem with the battery performance. This above picture shows that one set of cells has a serious over heating problem. The temperature reaches to 40*C while the ambient temperature is just 19*C. It seems the problem has to do with the bus-bar connecting the cells and the DC power cable that is laying above these cells.  Early analysis of the problem can save the battery pack from a damage.

FAQ: Getting the “EU” socket for EU standard products for 220V/230V

Most products sold in EU have the EU type socket: either the French style with the central ground pin, or the German type - Schuco.

It is quite easy to get the EU type sockets to be able to plug the EU standard products. Simply buy the EU type extension power-strip, and change the “plug-in” head to fit your local socket system. 

The top photo shows the EU extension power-strip with the plug-in head exchanged for the UK style socket. 

The bottom photo shows the same power strip with “traveler sockets” that allow to get universal type of socket (US, UK, China, etc.)

If you need to get the EU type power strips, be sure to contact GWL for help. We are able to purchase locally and resell to you.

IEC 60309  - 3 phase AC sockets

The industrial sockets for AC powering – based on IEC 60309. The typical household rating is 16Amp and 32Amp. With „C and D grade” of circuit-breakers, it may be possible to drain some 18 and 34 Amps from these sockets. It is also possible to take just one phase out from the 3 phase socket and  thus get up to 230V/34Amp power supply. This way it maybe possible to supply energy to high power chargers for DC applications.

Based on standard electrician and installation codes, equipment with 4kW and more should have a fixed cable installation.

Proper cable connection for the EVBike battery wiring is a must
We suggest all EVBike users keep checking connection the wiring of the EVBike battery holder. 
Improper connection will result in poor performance and over-heating.

GWL and deliveries of goods at fair prices to remote locations
Question: I want to order 4 pieces of the solar panels from GWL. I like your pricing. But when I add the VAT and the shipment costs, your price becomes higher. Perhaps if you make a 15% discount for me, I can buy from you. I am from a small village in Dagestan. 
Answer: We welcome customers from all locations. However our customers need to be reasonable concerning the expectation of the final pricing for the delivery. The shipping costs need to by paid, and the applicable taxes must be added This may increase the price, especially for small orders.  
Check following suggestions:
* Making a bigger order volume: we suggest increasing your order volume, by adding additional components to your order. This will split the shipping costs between more products and the final price of the individual products will be lower. 
* Share your order with more people: we propose to get some of your local people around you to share the order together. Perhaps you may encourage your relatives, your colleagues, friends or neighbors to buy similar products. When you mane one order together, you may reach an additional volume discount and share the shipping costs together.
* Find a local partner for regular co-operation with GWL: you may contact your local hobby shop or some other specialized company and propose to them to make the purchase from GWL for you. Perhaps they decide to get involved and become GWL local partner. This way the company may order at volume order pricing and you can benefit from this kind of co-operation.
* Start your own small business: Another idea is that you decide simply to go ahead, and to start offering the GWL products and solutions to people at your vicinity. This way you can soon reach the volume discounts and benefit from lower pricing.

Getting the water proof AC connector for the Micro-Inverter

Each microinverter is supplied with the AC line outdoor cable with two waterproof connectors. The Microinverter connectors can be easily removed to get access to the standard 230V AC wiring (brown - live - L, blue - neutral - N, yellow/green - ground - GND).

Also it may be possible to remove the connector on one end of the micro-inverter, insulate the open end and use the connector to make your own cable to mate with other connector. See also here.

Using the LP12V for starting agriculture machines

Sometimes it may be very hard to start some agriculture machine, like tractors, grass mowers or harvesters. The reason is that the original board 12V lead acid battery become “weak” when the machine is started very often or after the machine was parked the whole winter without any use. 

The LP12V batteries may be used as a simple solution to make a boosting starter battery.  The power of the LP12V battery is enormous and it will start the machine easily.

The Yellow Connector - Often repeated mistake of the EVBike installation
Recently we have had several customers making a similar mistake during the installation of the EVBike kit.  It is related to proper connecting of the yellow connector.  
Both the accelerator (had grip) and PAS (pedelec assisting sensor) have the same yellow connector. During the installation, please make sure, that the accelerator connector goes to the yellow connector on a handlebar (to the central cable) and PAS goes to yellow connector coming directly from the controller.

FAQ: EVBike Kits - which to choose? How to install the rear one?

Question: I want to get the EVBike conversion kit. Which type of the kit do you suggest: the front or the rear wheel?

Answer: we sell both types of kits. We do not prefer any type of the kit. The customer must decide which EVBike kit to choose. 

See some guide lines for the rear wheel drive kit: Even though rear wheel drive conversion may seem more complex and not that easy to install as a front wheel drive, it has these advantages:

  • The rear fork is stronger (this is a must for high power projects)
  • The disc brake fits more probably
  • The “motorbike” design and feel

See above the picture with a nine speed freewheel.  (The motor is the same dimensions as the EVBike 500W motor). You may need to use a washer to make a bigger distance between freewheel and motor (in case the chain interferes with the motor). Another washer might be needed for the other side of the free-wheel (in case the chain interferes with rear fork). These washers may widen the standard dropout of 135mm a bit.  However it is not a problem in most cases.

Question: Do you sell the 7 gears free-wheel cassette?

Answer: We do not sell the free-wheel spare parts any more. Customers prefer various brand types and sizes of the free-wheels: 6, 7, 8, 9. It is easier you can buy such a free-wheel according to your wish in your local bicycle shops.  

Note: please note that you must use a freewheel with the thread, not the cassette type! (see details here)
