It's a 40w CO2 laser from HPC Yes I have MyEnergi EDDI installed but it's more cost effective to export electricity at 15p kWh and import gas at 4.2p kWh so EDDI is currently switched off. Cost efficient in terms of equipment maybe but in terms of saving energy I wouldnt have thought so. I...

I'm not sure what output configuration your Fronious inverter has, I setup my system using an automatic change over switch similar to this:- Automatic Change Over Switch In the event of a grid failure, the emergency power output of the Growatt inverter feeds the Victron grid input, this then...

I'll have a nosey at that. I needed more than the 6kW I had installed due to the heatpumps I use, careful logic inside HA keeps us within our inverters capacity (11 kW Total). You should definitely go for EV UNLESS you have to drive 600 miles without stopping, tow a 3 tonne trailer and don't...

to be honest, I'd never considered that angle before until you mentioned it. In reality it will be even cheaper than I said, the batteries will go on well beyond the 8000 cycles but with a reduced capacity but the inverter, BMS and other associated equipment will continue to operate. In reality...

Thank you, it's working better than I expected. They were incredibly cheap and do the job well enough, £4.50 each in that well known auction site. I use them for other jobs too, the cooling water for my laser cutter the chiller is started and stopped by one of these too. In one of my former...

The 8000 cycles is the predicted life to 80% capacity so it can still be used at that point for a lengthy time. So, 8000 cycles at say 12 kWh = 96000 kWh. Dividing the cost 4200 by 96000 gives 4p kWh

Yep, that’s no problem, my system is logged on half hourly usage. I’ll post the data when I get home. Meanwhile, here’s what Octopus tell me from their analysis this month so far (pretty typical) My tariff is Intelligent Octopus Go.

Part II The isolator switch is in both +ve and –ve battery lines from the BMS going to the inverter, the fuse is also in the positive line between the switch and inverter. It’s worth mentioning that switching and fusing DC needs to be carefully specified. DC has the ability to maintain an arc...

House Supply With Battery And Solar I embarked on my solar and battery path when energy prices went ballistic in 2021, my contract had 6 months remaining my energy supplier informed me that my monthly payment of £178 would rise to around £530. There was no way I would (or could afford) such an...

FWIW I thought they were more humorous than political. Anyway, to stay on topic:-

I'll dig out all of my stuff and put it on here if it's ok with everyone.

Hubby goes off fishing, he gets set up, cast the line in and within 1 minute he’d caught a 10lb fish. He cast the line again, within another minute he’d caught an 11lb fish. He kept on repeating the process and caught a fish every minute all between 10 and 11lb, it was an amazing day. His phone...

I have an SPH6000 too, you can control it fully, it also has the emergency power output (the socket at the bottom of the right hand edge of the yellow labels in the photo. If you login to the shine app on your PC or phone you can get to the parameters. Here's my settings:- This is what you...

I have no direct experience of EcoWorthy, their batteries seem to be packaged cells which could be a quality brand like EVE or equally be trash. Reviews online (Trustpilot) come back with 2.7 and there are a substantial number of 1 star reviews. These reviews need to be studied to form an...

Apologies it's Eve not Evie, my mistake, we have a new granddaughter who is called Evie and my fingers typed her name rather than the cell manufacturers name. Eve cells are the acknowledged best LifeP04 batteries you can buy. I purchased mine in the UK from Fogstar, 16 cells to make up my...

This as you rightly say is not a good way to work your system unless youre running an agile tariff and your inverter is picking cheap times to charge your battery (probably not). These legacy systems are normally used with a dual rate electricity supply - peak and off peak. Timers and charge %...

I'm on Intelligent Octopus Go as well, 2 x EV (MG5 and a BMW i3). I have run my battery system now for over 2 years and my average energy cost is around 7.2p kWh. I use very little peak energy. Here's the Octoaid report from last month:- My batteries charge every night, all solar generated...

I'm not doing anything much at the minute other than a 'busyboard' for my 18 month old grandson - Wilf. He used one at a playgroup and I was horrified at the cost (£150+) of one so Autocad and the laser cutter will be in use for a couple of weeks. Something like this:- J
