The Fronius IG30 inverter that came with the house's original FIT 2.66 kV solar system, appears to have given up the ghost. Its reporting a state 104 error. It might well have been my fault as I changed my consumer unit over to MCBOs, and the error started when I rebooted. Im assuming its nothing to do with the change from RCD+ MCB to MCBOs (or my wiring!).
Im looking for a cheap second hand replacement but know virtually nothing about what to get for a hassle free DIY job. So far Ive flagged it needs to be 3kW, have a low DC Startup voltage and ideally have the same DC connectors (although looking at it it might be directly wired)
Any help much appreciated 🙂

I just checked my 15 year old panels output last summer and they never got above 2.5kV so maybe one of these would fit the bill? https://midsummerwholesale.co.uk/buy/solax-inverters/SolaX-X1-MINI-2.5kW-G3
