SSE advised there would be a Planned Outage in our area from 08:30 to 16:30, to enable the removal of tree branches too close to the power lines. I set the Time-Of-Use mode on the Sofar HYD5000-ES to charge the US3000C battery until 08:30. At 08:45 the power was cut, the Sunny Boy Solar...

The neon on a Crabtree 13A switched outlet in our house has "blown" (the glass is blackened) after about 50 years of use, was always on. Way back a "budget, unreliable" Curry's Matsui microwave was still going strong after about 30 years, it was too large for the kitchen where we moved to...

I have discovered that the EPS live and neutral to the two freezers from my Sofar HYD5000-ES are reversed: Live to Neutral 240V Neutral to Earth 240V Live to Earth 3V The non-critical circuits are correct, neutral to earth 3 Volts. I traced the connections back to the EPS terminals on the...

My inverter has a 13 Amp EPS output. I intend to cable this via a 16 Amp disconnector to a 2 gang socket outlet using 2.5mm2 T&E, to power a fridge-freezer, and a freezer. Spec for the fridge-freezer is 0.77 Amp, and for the freezer 0.4 Amp, with 1.4 Amps on defrost. Should I just rely on the...

My house has two 100A main fuses. Effectively one to feed the storage heaters. And one to feed the CU. Via an Off-Peak contactor system. 1. So for the Storage Battery Inverter to accurately measure the grid feed in/out, I believe I will need two Current Transformers, one on each of the 100A...

My old house has two 100Amp fused incomers to cope with six storage heaters on Economy 10. Here's my diagram. Direction of arrows and Low /Normal labels are my best guess and may well be wrong: I have a new Hybrid Inverter to AC-couple batteries to the existing Solar system. The Hybrid...

I want to add battery storage to my 12 year old PV panel and Sunnyboy inverter setup, the max-rate FIT applies. Is there a way to replace the Sunnyboy with an AC coupled Hybrid Inverter AND still feed the FIT generation meter with the full PV output ? I suspect the answer is no. So how does...

How much can I alter my 10 year old 3.2kw PV installation without the max-rate FITS payments being reduced ? For instance, if I had a battery system which required a new Inverter. Or if part of my house was able to run off-grid during a power cut. Thanks

I have discovered that our Friedland Bell & Chime Isolating Transformer (240v to 8V @ 1A) is powered from a 13A socket, which is spurred off the upstair lighting circuit ! Is there any alternative to ripping up the carpet upstairs and correctly spurring off the 13A ring ? A 5A round-pin plug...

Intending to have the house CU upgraded in the New Year, for safety reasons and to allow future expansion - EVSE etc. For my own satisfaction I have labelled the wired fuses and worked out what goes where, but haven't been able to find a house earth. It's a 1930's detached house on the...
