What it is
The KOOR All-in-One is a hybrid inverter and charge controller in one cabinet. It takes DC straight off the panels, charges a 48 V battery bank, and puts out regular 120/240 V split-phase power. It can run with the grid, without it, or ride through outages with the grid as backup.
Pick the size by the load, not the array: the 8 kW unit carries a house or a small shop, the 12 kW and 15 kW carry a dairy barn, a woodshop or a big off-grid home. Up to six can run in parallel from one bank for 90 kW.
The cabinet is NEMA 4X, so it can hang on an outside wall. Monitoring is built in: a Wi-Fi dongle ships in the box and reports to a phone app at no monthly cost.

Questions we get
Does it work without the grid?
Yes. It runs a full off-grid system on solar and batteries alone, with 200 % surge for 10 seconds to start pumps and compressors. Add grid or a generator later if you want backup.
Which batteries does it pair with?
Any 48 V lithium or lead-acid bank. With the KOOR 16K Pro or KOOR Active Stack it runs closed-loop over CAN, so the inverter charges off the battery's real state of charge.
How much solar can I put on it?
Up to 12, 15, 18 or 22.5 kW of panels for the 8, 10, 12 and 15 kW models. Three trackers, two strings each, 26 A per tracker. Keep cold-corrected string voltage under 525 V.
Can I run more than one?
Up to six in parallel from one battery bank — 90 kW. On a farm, a second unit is also a backup: if one ever goes down, the other keeps the milking going.
Can it go outside?
Yes. The cabinet is NEMA 4X and wet-location rated, from −25 °C to 60 °C. Keep it out of direct sun where you can; it derates above 45 °C (113 °F).
Is it UL listed?
It is certified by CSA Group — an NRTL — to UL 1741 with Supplement SB and to UL 1699B. Ask us for the certificate for your inspector.
What about monitoring?
A Wi-Fi dongle is in the box and reports to a phone app at no monthly cost. No Wi-Fi at the site? We supply a hotspot that covers it.
What is the warranty?
10 years from Fantastech Energy Solution LLC, the seller. Register the card that comes in the box.
