MyEnergi's Libbi Battery on Fully Charged show

Episode here.
I'm not sold on the need for a battery, especially when I'm selling energy for 15p to Octopus and buying it for less via Octopus Agile import. However, if my consumption patterns heavily skewed towards nighttime usage, or I had much higher consumption (EVs, heat pump), the Libbi seems like a quality UK alternative to brands like Growatt, Pylontech etc.
The modular capability and blackout protection are excellent pros. And the built in hybrid inverter will likely lead to system purchase savings. All at < £5K.
From Myenergi "The libbi will come with the inverter as a package which can be installed alongside your current inverter, you don't have to replace the one you have"

Is £5k plus installation a decent price for 5gwh at 3.6kw? I'm not convinced. The 5kw inverter seems the one to go for but no price on that afaik. I've registered interest but it's not getting my juices flowing. A bit of a risk too as it may be difficult to get service if myenergi disappeared.

It looks like a great product, but roughly double the price it would need to be to make any financial sense.0

Having already gone down another modular route, what looks like the biggest potential from the libbi is the software side of things and the integration for a whole house system.
If I was starting again I'd be very interested in the complete package from Myenergi.
If they can make it all work so that customers don't have to worry about getting the cheapest most efficient running of a system then that's fantastic.
Integration is worth much more than it seems.4.3kwp JA panels, Huawei 3.68kw Hybrid inverter, Huawei 10kw Lunar 2000 battery, Myenergi eddi, South facing array with a 15 degree roof pitch, winter shade.2 -

Integration is worth much more than it seems.There is more to come that may suit your current installation, including EMMA AI and an EV charger:I'm sure there will be others. Eventually. But they are unlikely to be quite so tailored to the UK market.

Once again those chaps have developed what looks like a great product with some great aims for collective collaboration in addition to probably superb property device integration.I agree though it seems over priced (based upon the post above) and yes there is the risk of all the eggs in one basket.Should myenergi run into problems ( not saying they will but it is a risk) then users might loose control and web access. That would be in a potentially similar manner to the previous demise of Immersun in its original form. Although that was picked up by another supplier, in some respects, that is no longer integrated or given the same support.It is also another system that seems to need web/unique app for info and control. I think systems should be supplied with a backup direct access option for when, not if web access fails, or support ceases. Many systems like this not just Myenergi products!1

Many systems like this not just Myenergi products!HiThat's always been a big issue to me ...It's not only a case of what happens if (/when) a company fails, but also what happens when you've paid for a pretty expensive product & the manufacturer/supplier moves the software element ToU towards a subscription based service ... what do you do?, accept the total capital loss & be determined to not get stung again -or- roll over, pay the money & accept that manufacturers are attempting to ensure that you'll never really fully own anything in the future ...If there's a definate web based service provision benefit to the customer/consumer, such as centralised monitoring or control, then that should not override the ability to fully monitor or control the system locally without any form of web access ... this would be one of the prime considerations on my shortlist & should be on anyone else's too ...HTH - Z"We are what we repeatedly do, excellence then is not an act, but a habit.

I can see the libbi being a big hit in the UK as it'll be sold as a complete system to lots of people new to solar.
Especially if Myenergi start installing or saddle up with a big group of installers.4.3kwp JA panels, Huawei 3.68kw Hybrid inverter, Huawei 10kw Lunar 2000 battery, Myenergi eddi, South facing array with a 15 degree roof pitch, winter shade.1
