Don't forget to factor in the power of your inverter and your tariff. If say, you have 6 hours of low price and can push 3.5KW in at a time, you can only charge up 21KWh of cheap electricity so oversizing the battery would be a waste without other generation capacity.
The tariff makes a big difference in my first year of solar and battery i was using 80% of my 15kWh battery in some of the winter days and constantly fiddling with overnight charging to minimise grid usage and cost, now with Intelegent Octopus Go i hardly every go below 50% and don't need to change anything and net zero cost or possibly in credit over the year
I would be interested in a second All in one battery but no inverter or gateway. 6kw in and out is enough. but more storage at a keen price that works in the givenergy family.
Great video I am about to pull the pin on your stack 3 battery with 3 phase inverter I live in Holland I use around average 16Kw per day I also have 16 3 phase solar panels on roof and plan to have a dynamic contract do you think thats a good fit , who is your main agent in Holland I am dealing with Accuselect at the moment they seem very good in their explanation
I wish this video had been available when I ordered my solar and battery system. I had no idea what size battery to get or what to base the decision on, and my installers literally didn’t care. I ended up with a single pylontech us3000c, nowhere near big enough.
Hi can you enquire within Givenergy the possibility of showing the actual KWH in the battery instead of a percentage, I ask this as my AIO had only been charging to 11kwh on a 100 percent charge ...hopefully now rectified by a re calibration
As others have said the inverter can be more important that battery size...if you have all electric cooking and an electric shower and only a 3.6kw inverter ( G98 - not G99 approval) you'll be drawing from the grid despite possibly having full batteries - and drawing from the grid at the most expensive time. Of course G99 approval is longer and pre install so makes the planning a bit harder. Good type of video to help people plan their system.
Its a bit more nuanced that that, snd somewhat more frustrating, as if you had the latest gen3 hybrid inverter, and say a 9kwh battery, yes the draw limit is 3600w's (this can be much less in earlier models) If you were to add another battery, the inverter would see it as a single 18kwh battery (for simplicity) but still only allow drawing (or charging) at 3600w's. If you had a 5k inverter, it's the same deal. It can only charge or discharge the battery at 3600w's. The 5k and 3.6k is more for when its working with Solar, and they can peak above those headline figures, but not when working with a battery
I'll admit I'm drawn to the AIO but am confused about the expansion options as a single 13.5kWh isn't big enough. But if an inverter, a gateway & multiple batteries provide the answer then capacity trumps convenience of AIO. Aim is for approx 20kWh ofstorage, full failover, option to add solar PV later.
Is there a way to have a removable setup? I rent but want a battery storage. I have an electric car and am on octopus. I want to be able to take my system with me if I have to move house. Thank you in advance
After getting our ASHP installed I may now decide to add a 2nd battery to our system. Correct me if I’m wrong but Gen 1 and Gen 2 batteries can both be connected to a Gen 1 inverter correct? Also will the new electrical regulations mean I couldn’t add a 2nd one into the loft?
I don't think EVM is allowed to comment on these vids for some reason. Yes I think they're compatible, but bear in mind with your gen 1 inverter (3.6 or 5k) that you'll still be limited by that 2600w charge and discharge between the inverter and battery. So you'd gain extra capacity, but not through put. Just thought I'd highlight it as it trips a lot of ppl up
Am I correct in thinking you can combine a GivEnergy all in one with an additional GivEnergy standard battery bank or would it need the upcoming All in one additional bank?
I've been told that the All In One cannot (currently) be connected to other types of GivEnergy batteries. In fact I don't think the AIO can connect to the extra AIO battery packs either yet - coming soon. I wanted to add an AIO to my existing 9.5kWh Gen 2 battery to increase my battery storage & boost the Inverter output capacity to 6kW+ because my existing 3.6kW Hybrid GE Inverter struggles to coup if we have two many appliances running at the same time. I was told that GE were working on this but it may not happen for quite a while (if ever) because the AIO uses a different architecture to GE's other systems. In the end I landed up with 1 extra 9.5kWh Gen 2 battery (19kWh total), 5 extra solar panels & kept my existing 3.6kW Inverter. Not ideal because whilst the storage is now good the inverter still limits how many appliances we can run without drawing the extra from the grid.
@@colingoode3702the issue is that you have two, or more, inverters connected to the same AC supply. A discharge from one will probably be seen as an opportunity to charge by the others - with unwanted side effects such as doubling AC-DC-AC losses and all the inverters “hunting”for their correct behaviour, but never getting it right. The correct solution is an overall control system (an EMS) that governs all the connected inverters. This is software and could be could be done in different ways to bring it into existing and new installations. You could for instance have the EMS code embedded in all inverters, then they do a built in election to decide which is in charge when they power up. Or you could go down the route of an external controller that would be an extra box to mount within cabling, BT or WiFi range of the inverters. The problem is relatively new. These are expensive installations in a still-emerging market. Not all that many people can afford dual or triple inverter installations in homes. Commercial installations are another matter. There you potentially need to scale to control far more inverters. GivEnergy were happy to show the monitoring page of a working prototype EMS at the EE show last week when I asked. No confirmed time to market, but it was working nicely in a prototype installation. There are a lot of steps between prototype and a full product.
Yes, this is one reason I keep coming back to the AIO. 6-7kw import so you can get a ton of cheap (often free!) early morning electrons, use some during the expensive 7-9am period, then charge again at lunch time before the expensive 4-7.30pm time. And 6kw discharge will cover cooker, tv, heat pump etc
It depends on the inverter you’re using, but typically a maximum of 3.6kW. That covers most of my use. Of course, when the oven is on, I don’t put the kettle on at the same time, so that I don’t draw from the grid. My whole family knows how to shift energy use now, and it’s easy to see on our smart meter display whether or not we are drawing more than the 3.6kW from the stored solar in the battery.
