Yeah shame but unfortunately he doesn't have the capacity to use them! Seplos and other batteries sitting there doing nothing. Looking at the garage he might have to do an off-grid warehouse garage channel soon! 😂 One thing Prowse did well was having every server rack and power station he had hooked up for long term testings! And MWh's of power generation! I should add that in Australia you can only feed 10kw maximum into the grid. As Andy is probably still under he's original solar contract it's just not going to change soon, nor is it worth it!

Hi Andy. Are all the different packs compatible to connect the BMS together? I have an Gobel GP-SR1-150 and someone tould me that is not compatible to the new GP-SR1-200 because a different BMS manufacturer.

Correct, the SR1-150 battery uses the Gobelpower BMS. The SR1-200 use the Pace BMS. They are not compatible.

[@Al-ix3vc]

Hi Andy , Amazing content but very overwhelming to a beginner! I have a couple of questions regarding BMS's. 1. is the software available to programme a PACE BMS to work with an inverter if I have the inverter protocol? 2. I have a Pace 15s BMS which is damaged, I need to replace it but I cant find one. Can a 16s work with 15 cells? Can I get 2 different BMS working in parallel? Thank you

[@OffGridGarageAustralia]

Hello, thanks for the feedback. You are starting right at the end of all my videos, so maybe not the best entry point... 1. Yes, with the PC software you can change the protocol in the BMS to sit your inverter. 2. not sure if the Pace 16s MS will also work with a 15s battery. I have asked Gobelpower that question and will update my comment Yes, you can have as many different BMS in parallel as you like as long as they have all the same voltage. So you cannot mix a 15s battery with a 16s battery for example. EDIT: Gobelpower has replied and it is possible by combining balance cable #15 and #16 together and se the cell number in the BMS to 15.

[@techmaster_sree]

2 Question's. 1- Bottom cell have imbalanced pressure right ?. I think the battery arrangement is not that good. its placed horizontally so the the bottom cells will have more pressure and is it recommended to use in this way ?. Will that accelerate the degradation of cells . I believe most of the manufactures are placing cells vertically in Powerwall design due this reason. 2- are you using raspberry pi to get the CAN data or this CAN cable plugged into inverter ?

[@OffGridGarageAustralia]

1. That's not a problem, the 300kgf compression will be much larger as just the weight of the batteries on top of each other. EVE states, the batteries can be used in any orientation just not upside down. 2. I use the Victron Cerbo GX to receive the CAN data. But this will also work with a Pi or any inverter, either CAN or RS485.

[@davesigz]

Love the Andy humor!

[@OffGridGarageAustralia]

What humour? 🧐

[@jogi_54]

7:58 f the german Standard for the torque testing is, to min double check this - and 2 colours for marking. At high voltage, starting with 6kV, we have 3 checks and 3 colours (must be done by 3 different persons). Anyhow - one dokumented check is better than nothing. BUT after such a transportation, all connections should be checked afterwards.

[@OffGridGarageAustralia]

Yeah, good advice. I'll check mine tonight as long as the cover is still open. Could not see any misalignments on these markers so I think it's all good.

[@jogi_54]

@@OffGridGarageAustralia ok - the second check will be done by you - so 2 persons will check it, what is really fair, to do it. (Remember, everyone of us humans can make mistakes - as well on the suplier side). Honestly in more than 99,99% we didnt find faults by double checking. But - especially in High Voltage Switch gears and similarly, any fault can cause extremely high costs in case of failiures (and additional very expensive time delays on a project....) As I worked as errection and comissioning engineer/manager of elektrical equipment, like switchgears - the first check was done at the factory, and 2./3. check at site after installation (which had 4th colour).

[@powerwall]

you have very good suggestion. in factory first one person will make the nut thread in, and then one person torque and mark, and a yong lady will inspect and note down.😄

[@johnmajewski1065]

I love your humor, Andy, as well as your show-off off-Grid Garage. In fact, I'm Off-grid not in a Garage but living on an ocean-going Sailboat. In your KZbin programs, one thing I learned that is the BMS are not reliable up to the tasks needed for the use. In my case, I have stayed with 4 x 215 amp AGM batteries and 720 watts of solar power. My question is what is the best compo of 12-volt safe lithium batteries and BMS. The fear I have, the BMS system will fail at the wrong time and leave me and my boat without power with a failed battery and BMS system. I'm more than happy to pay for your consulting advice as to what brands of 12-volt Batteries totaling 800 amps with a matching BMS to upgrade my boat system. I look forward to hearing from you.

[@OffGridGarageAustralia]

Thank you for your feedback, John. 4x 215Ah AGM batteries will give you only 4x 105Ah of usable capacity. So using now 4x 200Ah lithium is a massive upgrade in terms of capacity because you can now use almost all the 800Ah! I would not be concerned about a BMS failing once they are setup correctly. As you may know, I'm testing these products and drive these things in the wrong direction on purpose to see if they fail, when and how safe they still are... Especially in your case, you will have 4x 200Ah lithium batteries in parallel. Even if one fails, you have redundancy. Big benefit and the reason I went with three banks in parallel as well. So, any 200Ah LiFePO4 with BMS will do the trick for you. I would, however recommend a Bluetooth option for your batteries so you can keep an eye on the cells and also set them BSM up as you need them.

[@johnmajewski1065]

@@OffGridGarageAustralia Thank you, Andy, for the Battery/BMS compatibility assurance. I use Bluetooth now with my solar Victron controller and iPhone, it is wonderful tech.

@@OffGridGarageAustralia oh, thanks 🙏 i tried to find separate category, like a software 😀

[@LarryKapp1]

I have one of these Orient Power wall batteries to go along with the older Jakiper ( pre pro model ) batteries. The voltage runs a bit higher because those older Jakiper batteries did not have the better quality Eve cells. But all the Pace BMS work fine together . I will be interested what you find for cell differential when you charge full . I had set my charge voltage down to 55.2 but recently moved it back up to 56v and going higher after watching your last few videos. Hoping the bms balancer brings it more in tune. Well today the voltage got up to 56.5v and the differential on the battery was 110 mv differential. I don't think it went to OVP though. The older Jakiper I had used a Neey balancer to top balance in past ( not on it now though ) and it went to 45mv differential. Thanks for the video. oh Mine was bought here in USA in May and I did not get programming cable with mine or the signed inspection sheet - maybe that is a new feature or just for you - the bracket also was not in a separate box. ( but it was at a very good price so maybe they were clearing out the older stock).

[@OffGridGarageAustralia]

Thanks for sharing, Larry. 56V should be absolutely fine for this battery. The balancer has only a relatively small current of around 80mA, so it will take a while to balance it. 110mV delta is not too bad for 56.5V either and as long as no cell goes OVP, It will balance it out over time. More about this in the next video...

[@angyp74]

The bang for buck in Australia is woeful. $2500 for 5.1kWh won't stack up financially in most situations.

[@OffGridGarageAustralia]

ROI is around 8-10 years in AU for 2 of these batteries including a hybrid inverter and installation through a sparky. That's with the current power prices and existing solar. A work mate just installed it and shares the data with me...

[@restfulplace3273]

Licenced electricians in Au are not cheap. Watching the diy scene in USA is tempting as the total installed cost is much less. (Even allowing for exchange rates). The kicker is in subsidies and electricity rates, particularly time of day and peak feed in rates for virtual grids.

Wow, looks really well designed. Just makes me want to order one, even though I don't have a compatible inverter yet. Is this kind of battery pack suitable to put inside a home? LFP seems pretty good compared to NMC, and i do have a separate boiler room near the roof. But i'm not 100% sure this is a good idea. Putting it outside may be worse with cold wet climate in the Netherlands.

These batteries can be put inside, but please follow the regulations for your area when installing a battery.

[@SolAce-nw2hf]

@@OffGridGarageAustralia Thank you. I will get a professional to install it and go beyond regulations in terms of safety. This Jakiper brand looks like a very good option to decrease my dependence on fossil power. The only doubt now is if I should wait for sodium batteries as it's so close to reaching the market.

[@OffGridGarageAustralia]

@@SolAce-nw2hfDon't wait. Until Sodium will be on the market, it will take a few years. There are pretty much no factories being built right now to cater for that. I will test some NA+ batteries on the channel soon...

[@SolAce-nw2hf]

@@OffGridGarageAustralia Fortunately I can wait a little more because in the Netherlands we have a credit system. Every kWh that I don't use and is transported to the grid, can be used later within the same contract year without any cost. So that is a free battery for as long as this is allowed (at least until 2025). But I am going to add more solar panels on the empty (wrong facing) roof and will replace the Growatt inverter with a hybrid model as soon as I have a nice estimate of useful battery capacity. The other option would have been the brick and concrete garden shed, but I don't think that's a good idea for Lithium batteries. From all I have seen and read, CATL is planning to use the same battery form factor, which makes it easier to convert the existing factories. BYD is building new factories, also in India. And one other brand (forgot the name) is releasing a Sodium Ion car in early 2024. So I still have some hope, but your review and answer has given me enough trust in the Jakiper LFP batteries to buy it and not wait infinitely. My main goal is to use as little Coal/Nuclear power as possible, and this battery will enable that. Thanks again for your advice 😄

[@CollinBaillie]

Mostly because it's an international date standard. Not too many places have the month first as a typical standard.

It just takes a couple of seconds to slow down and think about it.
