How does GWL/Power support the customer’s co-operation?

How does GWL/Power support the customer’s co-operation?

We always look for partners who are active in promoting and supporting the DC-power solutions. These partners are usually individuals and companies who are creating solutions with the DC power components. For example the installers of home energy storage solutions, solar panel installers, boat installers, people who convert cars to EV, companies and business that use the lithium batteries for their products, etc.

See the ideas we published in the past:

We are happy to support such partners by special pricing and favorable delivery and payment terms so that we can help to make bases for sustaining their business.  When our partners create information about their work, we are always pleased to support the co-operation by directing customers to our partners.

Warning of the Internet Frauds

Warning of the Internet Frauds

We kindly remind the customers of the need to be very careful about some types of internet frauds related to payments and refunds.

In recent months GWL/Power has experienced some kind of attacks. Some hackers pretended to be the sales person of GWL and asked the customer to change the payment information to another account.   The hackers compromised the email account and sent faked emails and created faked modified order confirmations with a fake bank account.

We kindly ask all of our customers to take note of these illegal activities.   In case there is any change in payment details, it is always better to wait, resend the copy to more employees of GWL/Power and verify by phone, Skype or some other channels.

When making the payment, always verify the payment details as published on our web pages.

Mickey Mouse at GWL/Power Training
