Compatibility audit of your DC plant
We do one thing: we document what you have installed, and we hand you a signed sheet stating which lithium architecture fits it and exactly which parameters have to change. You decide what to do with it — with us or without us.
What you get
- The twelve-point compatibility sheet filled in for your site and signed: rectifier part number, controller model, firmware version, output range, charge profile, temperature compensation, thermal runaway management, string capacity, charge current limit, low-voltage disconnect, walk-in, and communications.
- A written statement of which lithium architecture fits your plant — 15S or 16S — and why, with the voltage arithmetic shown.
- The list of parameters that have to change on the controller before any battery is energised, with the values they have to take.
- Where applicable, a note that the controller firmware is below the version required for the settings you need — quoted as an upgrade rather than worked around.
What it costs
USD 450 per site. Commissioning, if you go ahead, is USD 350 per site. The audit is free of charge for the first ten accounts — we are building the compatibility database and your site is worth more to us than the fee.
The audit is yours whatever you decide afterwards. There is no commercial proposal attached to it and no obligation to buy anything.
Why we charge for it
Because it is engineering work with a deliverable, not a sales visit dressed up as a favour. A supplier who gives it away has to make the money back somewhere, and that somewhere is the quotation. We would rather charge for the audit and let you take the document to whoever you like.
Request an audit
Four of these fields are mandatory, and they are mandatory for a reason: without the rectifier, the controller, the firmware version and the number of sites, nobody can tell you anything useful — they can only guess. If you do not know one of them, say so in the notes and send a photo of the label instead.
