GivEnergy vs myenergi 

Price comparison is worth a look. Midsummer retail prices: Giv AIO: £6993 Libbi: £11893 Same approx batt sizes. But I’m in the pockets of GivEnergy apparently so don’t listen to me! 👀😄

Thanks - useful comparison..

Great informative video. I would say cost was the major choice in my choice of choosing Givenergy.

Loved the video, Oliver - a very concise comparison between the two manufacturers and their respective products 👍 I know many had concerns about MyEnergi's future given the recent redundancies, but I hear they've taken on some significant funding now, so hopefully they're here to stay! I have GivEnergy equipment myself and have had no real issues to date - it's great kit!

Myenergi Harvi is very useful for remote CT clamps where wired CT clamps for either the Zappi or Libbi are not feasible.

Good comparison Oliver! Interesting to see the 12 year warranty extends to the AIO as well. I believe that when it was released, it was only 5 years due to the inverter if I remember correctly? Shows the faith that GE have in their hardware. 👍

I opted some time ago for a Tesla Powerwall, this year I’ve add another Powerwall, combined now 27 kwh and will charge at night at 10kw they’ll also discharge at 10 kw If the house is using more than ten and there’s solar available the house first uses solar with the batteries making up the difference. Control is through an app and a very clever algorithm that charges the batteries at night on off peak electricity taking into account weather and my usage so that if the following day is sunny it won’t charger the battery right up but allow room for solar. The gateway also allows me to go off grid if I choose or the set the battery only to charge from solar, I use that in the summer, as well as backup if there’s a power outage.

Regarding the Myenergi Libbi solar it is 2.4Kw per MPPT string on the 3.68Kw inverter which is 4.8Kw total solar and 3.25Kw per MPPT string on the 5Kw inverter making it a total of 6.5Kw.

Good comparison. We couldnt justify the cost of Libbi to our clients so currently dont offer it. GE offer exceptional value

Does either of these have heating and cooling features for the battery? As i know some batteries havent and struggle to charge properly in winter (depending where the battery is located)

Good video also i wonder if in the future one of these groups swallows up the other to reduce competition

You can integrate the givenergy smart plugs with home assistant.. little bit of a faff but possible...

Yep price drove me to GE. I've just got a smallish 4.2kwh solar array but I love seeing the battery full and meter static or running backwards 😂. So far no problems and I hardly seem to be using any electric.

I feel like it was slightly unfair to GE to not mention the price difference between the GE and ME equipment. The GE equipment is a good 50% cheaper than the ME equivelents. Very much agree that Hot Water diverters feel less relevant now. Certainly at their massive cost. I very much regret my Eddi, as it now just acts as a glorified timer with some energy monitoring options TBH I have been really disappointed in ME in the last year or so. It feels like they were market leaders when the Eddi and Zappi were released, and that they have basically made no real improvement to their products over the last 5 years. Yes we have some a few hardware improvements such as built in Wifi and Hub. But still no local control, still a bunch of settings I can only control on the physical device. OCPP with the Zappi a) doesn't work locally, and b) doesn't work if your OCPP client actually does a schema check on the data as the ME response doesn't abide the schema strictly (And they haven't responded to my bug report on it).

I think the Libbi supports 2.4kW or 3.25kW solar per MPPT string - but there are two MPPT trackers, each with its own string - so does that not double the supported array size? I don’t have one, but a friend has just got theirs - I’m about to get my GivEnergy AIO & Enphase setup installed in a week.

The problem is most people will just get whatever kit/brand their installer can get their hands on cheapest - my neighbor has a right mismatch of different kit... Oh and I think you meant Type 1 (AC) for the older Nissan Leaf as Chademo is DC - Had one on my original Soul EV as well...

I had a 10kW Libbi, Eddi and Zappi installed this summer. What a BIG regret. My grid use went up 70% after it was installed because it is always importing from the grid and exporting when it shouldn't. I've been in nearly constant communication with MyEngergi Tech support but all they do is release updated Firmware that causes another problem. I don't know what Giv Energy are like in comparison but if I knew what I know now, I would have avoided MyEnergi like the plague.

I’ve just had a 10 kWh Myenergi battery system installed with a 5KW inverter together with eleven 400W solar panels. It includes a Zappi and an Eddi. Seems to be working well. Even in late October I’ve hardly used any peak electricity and some surplus solar has been used by the Eddi to heat the hot water tank. I’m hopeful that in the summer there will be sufficient surplus solar to provide about 8-10kW charge to an EV. Time will tell if it’s the right configuration but there is space for another 10 kWh of battery if that’s required but economically that doesn’t seem sensible at the moment given an EV can be charged directly via the solar surplus or overnight on the same low tariff mains power and the 10 kWh battery seems to match the overall yearly average house consumption. I do have some supplementary electric heating that I use, instead of the main central heating when there is spare electricity in the battery on good solar days. Maybe in a few years when I get a heat pump for the main central heating more batteries may be required. It’s all very interesting but quite a challenge to know exactly what combination of elements is required, until you actually use it.

Good comparison. I have a GE 3.6kW Hybrid inverter, 4.1kW 10 panel array, a 9.5kWh GE Battery, Zappi & an Eddi. All working fine since March this year except, 1. I need more inverter AC power to run more appliances & a future HP at the same time. 3.6kW output is easily exceeded by a washing machine, dishwasher, iron & an oven all running at the same time. 2. I need more battery storage so I can run the house for a whole day on batteries alone between night time battery charges. 3. I should have gone for more panels for extra afternoon west facing generation. Had the GE AIO been around when I signed up for my system this time last year I would have gone for that but alas it was not. I can add more batteries to my existing system (up to 28.5kWh) but I cannot increase the AC power output beyond existing 3.6kW. GE do offer a 5.2kW Hybrid Inverter but this is still limited to 3.6kW when in battery only mode so it does not give me anything better than I already have. The GE AIO is not compatible with their Hybrid systems so I cannot simply add it or mix n match components. I guess without spending loads more & starting from scratch I am limited to adding more panels & more batteries & that's about it.

I also like the accuracy of GE vs ME, as GE monitor true power where as ME can only monitor true resistive loads and not very accurate at inductive loads.

There were always going to be a few errors in my data, I knew that! So here are the corrections and clarifications collected from the comments so far: (After my quick plug for Octopus Energy - Sign up to Octopus Energy here using my referral link and we both get £50 credit if you do: share.octopus.energy/crisp-moth-619 ) - The GivEnergy inverters can take up to 5 batteries, not 3, giving you a maximum usable capacity of 47.5kWh per inverter. - The GivEnergy app will not currently provide local control if it cannot first authenticate against their cloud servers. This does not affect 3rd party local control (Home Assistant) - At the time of writing, the pricing of GivEnergy products is more competitive than the myenergi products, kWh for kWh or spec for spec. However pricing can fluctuate therefore I intentionally didn't include pricing comparisons in this video. Pricing is only one consideration and the extra expense of one ecosystem or brand over another might be worth it for you. - The Libbi supports two solar PV strings, each string with a recommended max power of 2.4kW (3.68kW inverter) or 3.25kW (5kW inverter), meaning it can support larger solar arrays than I suggested in the video (up to 4.8kW or 6.5kW). Of course the AC limits and battery charge/discharge limits still apply.

It should be pointed out that the GivEnergy App will not work in local mode if it cannot connect to the cloud - as was seen by a recent GivEnergy cloud problem. So, the local control is not fully local.

Thanks! Would the GE all in one work well with the Octopus Agile tariff?

How are you getting on with your AIO

EV Chargers. I don't think making a distinction between OCPP and Local Smart Control makes a lot of sense. GivTCP is an option for local control, but the Home Assistant OCPP integration allows you to run a local OCPP server - as long as you can configure your charger to speak to the Local OCPP, you've basically got equivalent functionality.

5 batteries on Giv Hy max 47.5kWh 😂

Octopus paying 15p per kWh for exported solar makes batteries uneconomic. And so no such thing as “free hot water”.
