Thanks very much to Infinite Energy for a quality job. Excellent work by Electrician who laboured all day with hardly a break to achieve a neat installation of battery, inverter, fuse box, solar generation meter and 4 isolator switches. He hefted very heavy battery and inverter into place after politely negotiating where they could be fitted. Took away all waste for sorting and recycling back at base. The panel installers were also polite and completed their task in strong winds just before the heavy rain came down. In addition they installed two panels higher up the roof than on the plan to capture more light. I had paid a 25% deposit to Avanti Energy who went into administration a month later. Safe World Insurance sorted everything for me for which I am grateful.
