Warranty

Sold and warranted by Fantastech Energy Solution LLC. Keep the warranty card and your invoice together — both are needed for a claim.

What is covered, and for how long

  • KOOR All-in-One hybrid inverter — 10 years
  • KOOR batteries — 10 years (16K Pro and Active Stack)
  • KOOR off-grid inverters — 5 years (12K)

The warranty covers defects of design, components and manufacturing. The term runs from the date of installation, and in no case more than six months past that term from the date the unit left the factory. It applies to units bought from Fantastech and installed at the address on the card, and is non-transferable unless Fantastech agrees in writing.

How a claim works

  1. Report it within 14 days of the first sign of trouble: call 574-218-1973 or email derek@fantastech.org.
  2. Send the warranty card, the purchase invoice and the installation or commissioning report.
  3. Send pictures and the fault code or fault screen. It is the fastest way to get a unit moving.
  4. Fantastech decides whether the unit is repaired on site, repaired at the shop, or exchanged for an equivalent replacement. The remainder of the original warranty carries over to the replacement.

What is not covered

  • Incorrect installation or commissioning, or not following the manual
  • Unauthorized modification or attempted repair; a broken product seal
  • Reversed battery polarity or the wrong battery communication protocol
  • Insufficient ventilation; not observing safety regulations and electrical code
  • Lightning, over-voltage, storm, flood, fire
  • Transport damage and cosmetic marks that do not affect operation

The warranty covers the equipment. It does not cover labor, travel, lift or crane rental, lost production or other direct or indirect costs unless Fantastech agrees to them in writing beforehand. Your rights under statutory liability and product liability law are unaffected.

Monitoring

Every KOOR inverter ships with a Wi-Fi dongle in the box. Plug it in, join it to the site Wi-Fi, and the inverter reports to a phone app — production, battery state, faults — at no monthly cost.

No Wi-Fi at the site? We supply a small 4G hotspot with a free data plan that covers what the dongle needs. One per inverter location, no monthly bill.

Common questions

Which KOOR battery goes with which inverter?

Either battery works with either inverter. The 16K Pro and Active Stack are the same 16 kWh pack in two housings — a cabinet on casters, or a stack you carry in by the section. Both run closed-loop with the All-in-One and the 12K over CAN.

Can I mix KOOR batteries with another brand of inverter?

Usually yes — the batteries speak CAN and RS485 and pair with the major brands. Ask us for the wiring guide for your inverter; we have written them plug by plug for several.

The inverter and battery are not talking. What do I check?

Nine times out of ten it is the wrong jack, a bad cable, or two batteries on the same address. Check those three before anything else, then call us with the fault screen in front of you.

Where do I register the warranty?

Fill in the card that came in the box and send it with your invoice to derek@fantastech.org, or mail it to 3645 S 1200 W, Goshen, IN 46528.
