Hi Flyfisherman Looking at the following document they only state this for the A48100, interesting what you say on the BX51100. SA-version-Dyness-Warranty-Terms-LV-battery-2022-02-1.pdf (solarwaysuppliers.co.za) In reading this, my understanding would be that all the other Dyness batteries models are still eligible for the 10 Year warranty. Can anyone else confirm this? are there any members here who work for the Dyness suppliers? -Giggsie

Good morning Power Forum Members I have been a member here for the last 3 years while reading up and most importantly saving up before embarking on my Solar installation which I have somewhat begun with the purchase of a 2nd hand GoodWe 5048D-ES 2 months back. I am now at the point where we have the funds to buy some of the Pannels and batteries to get us started and then start to look for installers to quote on the installation. My goal with this post is to share the ideas I have in my mind and draw from the experience of the members on this forum. please feel free to make suggestions/comments on what needs to be addressed so that I save myself some heart ache and school fees. Here Goes: Solar Panels and PV Components So, I began with measuring out our roof space to see how I could optimize/maximize the area I have at my disposal. This was a painstaking process (Hours and hours and hours in SketchUp and reading the spec sheets for different panels) as I went through all the different manufacturers and sizes to find the best fit. Here is what i landed on: JA Solar and Canadian 360W to 380W Panels Landscape configuration x16 Jinko 470W/475W Panels in Portrait configuration x14 I was really keen on the All-Black option on the Canadian Solar and JA's but stock availability is an issue plus I can get the Jinko's for around the same price. Jinko Solar Panel Tiger 470W Mono-Facial – Solar & Inverter Warehouse (inverter-warehouse.co.za) I have included a snapshot of the roof install Panel Layout below and welcome any comments and advice. this section of the roof is mostly north facing with only the small section bottom left with shading in the morning hours. As a start I am looking to buy 8 of the Jinko's and then add the extras at a later stage when we have the extra funds. I have already built 2 in 2 out PV Combiner box with 4x ZJ Beny fuses (Looking to use 15A fuses in these) as well as 2x ZJ Beny SPD and 2x ZJ Bent 2 pole 63A DC Isolators. and my idea is to use 6mm Solar PV Cables from the Panels to the inverter. Batteries On the batteries I have tried to use the list of supported GoodWe Batteries to drive my choice here. I have worked out that our house idles at between 350 and 500W over night and with running the TV, Laptops and a few other appliances we should use a max of 9KW overnight. With this in mind I am favoring the following batteries: Dyness Powerbox Pro 10.24KW (85% DoD) x1 Dyness BX48100 (90%DoD) x2 Dyness BX51100 (80%DoD) x2 I also like the Dyness as they would save some money as i would not need to buy additional brackets or cabinets like i would with the PylonTech US3000C units. The trouble I am having here is deciding which of the 3 is a better option. I would ideally like to have the 90% DoD but my plan is to only run them down to 80% DoD in any case so not sure if I am just being pedantic about having the extra 10% for emergencies. I am leaning more towards the BX48100 as they have a smaller footprint than the Powerbox and this will give me the ability to add a 3rd at a later stage if I need the extra backup (I also like uniformity). Wiring inverter into the DB Here is where I need a bit more guidance and advice. Not planning to do this on my own as I want the CoC and insurance and warranties so will be looking for an installer to assist but I also don't want the clutter of Surface mount DB Boxes littered all over the wall. I have quite a bit of space available in the top row of our Main DB and if possible, would like to have the GoodWe Power Meter, Inverter Breaker, Change Over switch and Essential Loads breaker installed in this space. Does anyone know if this is allowed? I have asked this question on the following post and would appreciate any comments and advice here. Again, I am a fan of neatness and simplicity so don't want to be steamrolled into adding extra components if they are not completely necessary. This will also help me decide where we position the Inverter and battery bank and possibly look at chasing into the wall for flush mount options in preparation for the installation. I would also appreciate any recommendations for reputable installers who hold the qualifications to ensure the warranties of the equipment will be honored, who are reliable and would be willing to assist in performing the installation of the equipment above. Thanks in advance.

Morning All I am in the final stages of my solar install and would like the forums input on the wiring of my Goodwe 5048D-ES Inverter into the DB. Can i use the Extra Space in my current DB to House the Breaker for the Inverter, Backup leg, Change over switch and the SPD (Oh and the Goodwe Energy Meter)? I have attached a photo of my DB in its current state to show the space available on the top rail that I would like to use for invert feed into the DB. The plan would then be to move Lights and Plugs to the Backup Leg and then leave the Stove, Geyser and Pool on the non-backup all within the same DB. Would this be in line with regulations? Or does everything have to be housed in a separate DB? Apologies if this has been asked and answered before, I have tried searching the forum and have not managed to find a clear answer on this. Your advice will be greatly appreciated. Thanks,

If you dont have daily tracking from winter last year will have to look at you electrical bill for last year at the same time and then average out the monthly usage. My guess is you might climb by an extre 2 to 3 kw. We averaged 13kw in the summer as a 5 person house hold in the summer. No solar geyser. No solar anything. Now with winter here and having to run the geyser longer we up to 15 to 17kw per day. Also when our gardener is here with the use of the lawn mower and leaf blower and running the outside geyser so he can enjoy a hot shower we also consume and extra 3 to 4kw onthese days. Hope this helps in some way in your estimates.

Hi Henk. Is this inverter still available? Thanks

Ditto.. price dependant i may also be interested in 1.

Last Question, is there a way to work out the heat that will be generated by the Battery and Inverter? The question came back from one of the SGB parents as this solution goes into a strong room. There is no aircon to regulate heat.

Another Quick question on the configuration of the Kodak Inverter with Battery to build the UPS, Should this have a configuration have a fuse or any type of breaker switch between for compliance?

Thanks @jumper, really value the input and guidance. A quick question on the Shoto and Kodak Coms, would using something like SolarAssist help to bridge the gap?

So I know I have let this thread run dormant but I decided to reach out to a few people to assist on this, sadly with not much luck. Everyone seem to want to up sell solar or a managed solutions or some form of rent to own. I have met with and spoken to at least 10 different parties and only have 3 quotes none of which match the requirements I provided above anomaly focus on the primary location/Main server rack. So it would seem I am back to where I started 4 months ago. Before starting this thread, my initial thought was to go for the RCT 3KVA inverter with 24V LFP Batteries (Any brand): https://www.enway.co.za/Inverter/Off-grid-Inverter/Alfa-3KVA-2.4kW-Pure-Sine-Wave-Inverter-Charger-pwm?limit=100 But since I can't find data on how well this works with LFP batteries I am not willing to take the risk and experiment with money that is not mine. This was also before @Steve87 and @jumper's replies. So after the messages here I think I will be better served by the Kodak connected to a Pylontech or Dyness 2.4 or 3.6Kw battery: https://www.solar-shop.co.za/kodak-inverters/581-kodak-solar-off-grid-inverter-with-ups-5kw-48v-rack-mounted.html Based on the load in the server rack at the primary location I should get a run time 6 hours and up based on a load of 400W. This will also give room to grow as I can expand on the number of batteries if required down the line. For the other locations: I conducted a test with the facilities manager using his Jackery Explorer 500. This showed that the 2nd location is actually only drawing 100W as we don't need to power the TV for the camera system after hours which will give us the 5 Hours run time and it can be charge back up to 80% capacity within an hour. https://jackery.co.za/product/explorer-500-portable-power-station/ The down side is that it uses Lithium-ion and not LFP cells and is only rated for 500 cycles. I then came across the Bluetti EB70 on take-a-lot and thought this would be ideal until I read the comments: https://www.takealot.com/bluetti-portable-power-station-lifepo4-1000w-716wh-eb70/PLID92530246 Apparently the power Pack is quite noisy and since the 2nd location doubles as an office I don't want to introduce something that will result in a noise complaint. It is a pity as these make use of LFP cells and rated for 2500 cycles. I suspect it will be fine for the Store rooms where we have the AC Network Switches as I doubt the noise will be heard from the outside. So I am back to looking for a solution for the Office/2nd Rack. I found out that the PoE switches for the Camera systems are 4-port and not 8-port like was originally told to me by the installer. So I am looking at these little DC UPS sold by Tech-Buddies which I came across some time back but thought would not work as based on their website they could only run the 8-Port config for approximately 2 hours. https://tech-buddies.co.za/prestashop/home/39-power-buddie-mini-dc-ups-48v-12v-9v-75wh-poe.html I have reached out to them to get their feedback on the feasibility of being able to run this load for 4 hours and they feel it should make it but have agreed to come to site to run a test with us like we did with the jackery to make sure it can carry it. So this is where I find myself at this point intime after scouring forums, listening to different points of view and advice from anyone and everyone I can find who has knowledge on this topic. Again, any insight and advice that can be offered by the members here would be welcomed as I would hate to put this proposal to the school and it fail and be a waste of money.

Thanks @Steve87, great to have experienced input on this. Will try look at the 5KVA 48V option.

Great point, Had not considered that.

Thanks for the suggestion however would a 5KVA not be overkill cost and function wise for the above loads? It just needs to fit in the cabinet and look neat and tidy. Rack mount would be a bonus but not a requirement. I can also add in additional shelves to cabinets to house the extra equipment.

Good day power forum guru's I am in the process of trying to build a solution for our school's network mainly brought about by needing to keep the security camera system online during loadshedding. We have 2 main network consolidations where the NVR, Server and core switches are located that will require backup power for 200 and 400 watts respectively. Then we have 2 network cabinets in storerooms with 2 switches each that we need to power, both rated at 30W so it would be 60W per cabinet. Then we have 2 8-port POE switches that are in 2 separate classrooms that provide power to some POE Security Camera's that will also need to be powered. I am looking for something that will fit into the cabinets and still be "aesthetically pleasing" so I am not a very big fan of the Trolly backup solutions as this will likely have to sit next to these cabinets and take up more space where we are already constrained. Added to this it needs to be cost effective because of budget constraints and be something that they won't need to replace batteries, etc. in a year or 2 and ideally have a quick recharge time to get back up to power before the next outage. I am trying to spec this for the Stage 4, 5 and 6 type outages. Any suggestions on products that out there that anyone has used for a similar scenario. Really appreciate any input and advice.

Hi Gunners. If you were to sell the batteries seperately, how much would you be prepared to sell the inverter for?
