Caddy Posted January 30 Share Posted January 30 Been looking at battery options with the upcoming change to the VAT rates on them to see if they make sense yet. I've seen this company on a few You tube videos doing some pretty complex installations and thought to have a look at what they offer. The 15Kwh Big Lemon system with all Victron kit and their battery seems a nice bundle and the price is competative. Anyone used this company before? I think they are based on the south coast near Bournemouth. https://lemonenergy.co.uk/products/15kwh-battery-5kw-victron-ess Link to comment Share on other sites More sharing options...
JohnMo Posted January 30 Share Posted January 30 Main thing for me is would it run the house or just a couple of circuits if mains suffers a power cut. Does this? Link to comment Share on other sites More sharing options...

This is the data for the inverter https://www.victronenergy.com/inverters-chargers/multiplus-ii Link to comment Share on other sites More sharing options...
Bramco Posted January 30 Share Posted January 30 @Caddy - that looks expensive. You need to add an inverter as well. Also, watch out for the larger batteries - that Lemon one must weigh about 150kg if it's 15kWhs. We recently installed a Sunsynk 15kWh system bought from ITS for just under £5k, including the inverter and with VAT and delivery. This was a self install, so we had to pay the VAT. Don't forget if you want to take advantage of the zero rating for VAT, it means that you will probably have to have an MCS installer do the work and that bumps up the whole bill by quite a lot - generally a big chunk more than than the VAT you would pay on a self install.

But most hybrid inverters seem to have this capability - some more flexible than others. Our system with the 5kW inverter handles all our daytime needs, we charge from solar and Octopus Go cheap rate at night if needed. Simon Link to comment Share on other sites More sharing options...
Originaltwist Posted January 30 Share Posted January 30 I don't think there is startlingly good value here. A Fogstar 15kW.hr battery and a Victron Quattro-II would be under £5,000. This would be more versatile but you'd need to forget the string inverter idea for PV panels. Spend the saved £2,300 on some panels with Enphase micro-inverters, or maybe you already have some panels. Link to comment Share on other sites More sharing options...
Caddy Posted February 5 Author Share Posted February 5 I need to stop looking at batteries, the sums just don't add up in my favour. I don't have an EV and I'm too light (tight) a user of elecric to make them economical even being all electric having solar, immersion heater and a heat pump (A2A). The lure of new tech to play with is battling with my common sense. Link to comment Share on other sites More sharing options...
