Most questions here are answerable in one reply if the message carries four things: the pack, the inverter it has to work with, the quantity, and the destination. Without them the first reply has to be a question, which costs a day in each direction.

Getting a useful reply

Questions this raises most often.

Which channel should I use?

WhatsApp for a quick confirmation, a photograph of a label, or checking that something is in stock. Email for anything that needs a drawing, a specification, a written quotation, or a record you can refer back to.

What makes a first message answerable in one reply?

A model code or a clear description of the pack, the inverter it has to work with, the quantity, and the destination country. With those four the reply can be an answer; without them it has to be a question.

Can you check a BMS and inverter combination before I order?

Yes. Send the inverter brand, model and firmware version along with the pack series count and continuous current, and the protocol and cable can be confirmed rather than guessed.

Does sending this form create a support ticket?

No. The form opens a pre-filled message in your own email client, so nothing is stored here until you send it and it arrives. If you do not use a desktop mail client, write to the address above directly.
