Paired with 3.68kw hybrid solis inverter

Are pylontech batteries any good? One installer says really good, another says full of problems

Someone is saying that because it's a "battery only install" and no solar, it needs to be the solis 3kw AC coupled inverter, the 3.68kw inverter is DC and not suitable. Is this right? I can't have the 3.68kw inverter as battery only install?

I appreciate all the replies here thank you everyone 😊😊

I don't know what's max for residential, but they email me today saying will need to upgrade/increase my fuse So the only issue with G98 compliant is that the inverter would be 3.68kw? I'm looking at my bill and most of the day I'm always less than 1kw usage. Only goes over 3kw when charging car at night. Maybe 3.68kw inverter will be ok for my needs

Not planning on getting PV. Don't want to risk anything on the roof. I'll be happy with 7.5p peak charges with battery. DNO just came back to me following my EV charger install last month.. Saying they will need to do fuse upgrade (currently 100amp) and also service cable replacement to cope with increased demand. Also they're saying I'm looped so will need to do neighbour as well 🤣😭. Lucky me 4 month wait. Looks like battery install might have to be delayed?

Octopus intelligent go tariff

Been quoted £4500 installed

Thanks for explaining. Can a person like me who knows nothing about electricity apply? Or would the electrician need to? What would have happened if they installed without permission?

Next thing is about DNO. The electrician said no need to inform DNO as nothing is going back to the grid. Other companies are saying need to do an application for G99 Someone else said can just do G98 application Which is right?

So I use around 20kwh electricity over 24 hours (when not charging my EV 5kwh off peak and 15kwh peak 15x30p = £4.50 daily = £1638 yearly 15x7.5p = £1.13 daily = £409.50 yearly Equates to £1230 saving per year If battery/inverter fees are £4500 for above system then just under 4yrs ROI If battery/inverter fees £6500 for pylontech instead of seplos then just over 5yrs ROI Battery life 6000 cycles so still should be good for a while (hope my calculations are correct!)

Yes uk.. Fitter is advertising on ebay with 15.5kwh seplos battery. Are they reliable and good quality? Any issues? Thoughts on the solis inverter?

Hi everyone. I'm new to this site. What are your thoughts on a battery storage system with 5kw solis inverter and 15.5kwh seplos battery? Just want to utilise the cheap night tariffs to charge battery over night and use it during day. No solar panels. Look forward to comments on the hardware Thanks
