I need advice from an electrical expert in the heat and light areas mentioned below with 3 issues:: 1. Disposal of large Lipo battery for recycling 2. Fault with Solax battery inverter system. 3. Integrated control electronics I have had 4.5Kw Solaredge roof panels for over 8 years installed by a company recommended in Bristol, that continues to be troublefree after one panel's micro controller was replaced f.o.c. My independent solar battery installation is now nearly 5 years old. The installer went bust so no help from him. It uses Solax batteries already replaced once, free new batteries supplied by Solax under warranty and installed by me. I am stuck with a big old Lipo battery and can't find a way to get that recycled. Any ideas? Now the online monitoring for battery inverter is showing no functionality at all so I suspect an inverter or communications fault. While I am a retired professional electronics engineer I have temporary eyesight problem which precludes me doing much. Can you advise how I can get this sorted? If the Solax battery inverter is OK and it is a comms problem I would really like to have an integrated monitoring system which talks to 3 systems: Grant heat pump, 2 years old Solar Edge roof panel inverter, some 8 years old Solax battery inverter, some 5 years old Is that feasible?
