Its in the UK.

Looking for any insight on this battery, its used and could have been manufactured 6-8 years ago going by other listings by the same seller. This is substantially cheaper that buy similar battery new. Any advice will be appreciated

Many Thanks for the detailed Post Plonkster, very good point about the micro inverters being on the roof. I ll have a watch of the webinar and rethink my options. Many thanks.

Hi All, I have searched the forum but can seem to find the answer to my question. I am looking to build a new Solar install l for a new property and I am considering using micro inverters as against normal inverters, specifically this one WVC-600 with the aim of maximizing the output from each panel, I ll be looking to install roughly 12 panels at least. I have heard micro inverters tend to last longer up to 20 years as against about 5+/- years for ordinary inverters. So I intend to use backup batteries and the system will not be fed back into the grid, grid will be used when available but nothing going back to the grid. I understand how the setup for a standard inverter setup will work, just need to know how the wiring if a micro inverter is used will look like. My questions are:- 1.) Can I have battery backup if using micro inverters 2.) Do I need a seperate Inverter to actually output the generated power either directly from the Solar panels or from the battery when consumed since the micor inverter will be placed on the roof next to the panels. 3.) Any idea what the setup will look like. Delails of the inverter below, it accept 2x300W panels. cription WVC-600 Solar Micro Inverter Pure Sine Wave Solar Power Inverter 180-260VAC Description: WVC-600 (Wireless Smart) adopts IP65 waterproof streamline design to prevent rainwater from eroding on the surface.

Hi Again, So Systems has not been fully installed, in my absence a lot has happened. So it turns out the Panels that were installed were infact 150W panels as against the 200W earlier discussed so we currently get about 60-66 VOC. I am not haoppy about this obviously and I have been offered 2 Options, 1. 1. Supplier to extra panels to match the 6 already installed to make it 4 strings each specs more like what below Or Option 2 Take back the panels and refund.. (Ideally preferred but way too much hassle) If taking the extra 2 Panels will be fine, I dont mind really as I can put this down as part of the learning Curve. Any advise will be much appreciated.

Many thanks for your help, so just to clarify, this cannot be used without a separate Solar Charge Controller with my current Flooded battery setup. Option 2 would sarcrifice the Longitivity of prolonging the battery bank. This is still a learning process for me and I would not repeat this when I want to do my own install.

Hi All Again, So installation is currently on going now and the installer engineer has just advised me that the Axpert MKS PLus 3KVA inverter (Hybrid) does not have a built in battery equalizer feature although I have bought the HA02 battery Equalizer/balancer but he insist I need a solar charge controller which will equalize the battery? He said I have 3 Options: 1. Buy another Seperate Invert and seperate Solar charge Controller 2. Use AGM battery instead of FLooded Battery US2200 battery 3 Buy a Seperate MPPT Solar charge controller (This defeats the purpose of going Hydrid) I am in a bit of a pickle . I need advise from the experts. Note: Axpert Manual shows Flooded battery Options Under Battery Settings (default is AGM) could it mean if Flooded is selected there is no need for a seperate equalizer

One more thing guys.. Install is planned for this weekend and there is talking about grounding and Lightning arrestor. Can you knowledgeable people advice on this on this please.

Many thanks for the above, just thinking out loud here..in order to store more energy what if I decided to go down the route of 8x 6v batteries to arcieve my 24V and connect in parallel to achieve 480AH power bank as against 410 bank, how would this affect this calculation and also, is there any drawback in this option as I read somewhere about the point of connecting multiple batteries could be point of failure.

That would be a deal breaker certainly.

That is most certainly kind of you sir! But I am in the UK. Sent from my LG-H850 using Tapatalk

Having looked on eBay here, seems it's quicker and faster to get the mc4 y connectors for now, seems anyone will do is that right? The combiner box I found also came with a 10a fuse, would it be okay to just change the fuse inside the box? Sent from my LG-H850 using Tapatalk

Aren't you a rock star..

Mine is the one here the Plus Model which support max 1500W array output

Ooops 24v one.

Hi again, I am at the final phase of this and have opted to double the battery bank to reduce the DOD to maximum of 25% I have done my calculation and they only really need to use battery for roughly about 10 hours. SO I am now buying 4 x 12v 205AH US battery and 6 x 200W mono panels. (I intend to add more later) Axpert 3000KVA MKS PLUS inverter supports (1500W PV array). IS there any special way to connect the panels to utilise the panels to the fullest. attached is the specs from the proposed panels. Thanks in advance.

As far as batteries go, I can get a trojan 105 12v 205ah @ equivalent of 4,587.15 ZAR or a US battery 2000 6v 125ah for 2,866.80 ZAR and that is due to the unstable economy mainly the forex issues. How does these compare to SA prices. Sent from my LG-H850 using Tapatalk

Thanks once again for taking the time to reply. I believe my Dad should be able to follow the maintenance procedure, He is usually religious about this kind of things so that's good. Eskom = (PHCN in Nigeria) is very unreliable but will be wired as backup for usage and also to charge the battery if required as well. Reason why I asked the question on the battery was to determine if there are any benefits to adopting either 4 or 2 setup but like you pointed out, more cables and higher potential of failure. Overall thanks for your time. Like I said I have spent some sizeable amount of money on new TV and Freezer purposely to take the overnight load down as much as possible. I also intend to install a timer switch for switching the freezer and fridge off in the evening when the sun is down for them to start again in the morning when the sun is out in order to reduce the overnight load to possibly lights and maybe a small fan. PS: I mentioned my brother as he will sure knows better than my dad when it comes to electrical wiring and reading and understanding whatever is displayed on the control panels, he might not be able to fix it, but sure knows. :-) I intend to get a timer switch to make these work only during the day and off at night to possibly reduce the DOD drastically at night.

Sigh. Where do I start probably first by thanking @TTT and @Plonkster for the time spent replying to my post. I would very much love to go the Victron way however I have had to shell out on some less power hungry electrical equipment in preparation for this project namely a new TV, previous one was 200W old sharp from 2007 to a 55W Sony, same goes for fridge freezer and fans hence my budget has depreciated to about 2K absolute maximum. I thought of buying directly from the UK however the added cost of shipping has made it not a very good option plus warranty might be an issue if needed. Hence my decision to go for the axpert plus my brother who is an eletcrical engineer can be summoned if required, he also currently uses a Gen/Grid battery powered solution himself. Aside of this project, I am also in the planning phase for a poultry farm which I intend to be completely an off grid solution.

Would one balance be sufficient for this 6v x 4 battery setup? I can see one on ebay http://www.ebay.co.uk/itm/BALANCER-BATTERY-6V-Part-Number-CEQ6A-/390586040875?hash=item5af0be022b:g:M~8AAMXQatBScAz9 I assume I can purchase one using the connection on the right side.

I ll appreciate any further advice re my questions above. Sent from my LG-H850 using Tapatalk

Many thanks for your reply. I do not want to push Power back to the grid. I just want to recharge the batteries using grid as source when available. Sent from my LG-H850 using Tapatalk

Hi All,­ ­ I came across this forum by accident and ­it seems to be the best accident that has­ ever happened to me. The information I h­ave read on this forum in the last few da­ys has surpased everything I have read in­ the last 4 weeks! ­ I live in the UK but my parents’ lives in­ Nigeria and due to the erratic power sup­ply I am in the process of installing a P­V/Inverter battery to make their lives ea­sier to require as little maintainance as­ possible. ­ I have read so much in the last One month­ and have decided to settle down to the f­ollowing: ­ 1 Axpert 3KVA Plus Hybrid Inverter­ ­ 4 x US 2000 XC2 Flooded Lead-Acid 6V 240A­h or (alternative Trojan J185P-AC 12V 20­5Ah if there is any benefit in a 2 batter­y setup against the 4 battery setup)? ­ 6 x 250Watt Mono Panels­ ­ ­ ­ My questions are:­ ­ 1. I have heard that flooded battery need­s to be topped up roughly once a month an­d then equalize? would my Axpert inverter­ be able to do this equalization or do I ­need to get another device to do this. ­ 2. The usage would mostly be for lighting­ (low energy bulbs + fan) so I intend to ­keep the DOD of the battery at a max of 5­0%, would there be a way to setup the Axp­ert inverter such that the inverter stops­ working once the battery DOD threshold h­as been exceeded? ­ 3. From my lay man's point of view, I bel­ieve a 4 battery setup is better that a 2­ battery setup for the same 24V, please a­dvise if this is the case or not. ­ 4. I also intend to feed the utility from­ the Power company into the inverter so t­hat the battery is harged whenever there ­is power supplied but nothing back to the­ grid, is there a setting available that ­requires very little maintainance except ­for the occassional battery top? ­ ­ ­ That would be all for now, I will post an­y further questions that come to mind, pl­ease feel free to make recommendations as­ approiprate. ­ Thanks in advance.­ ­ dejavus­ Sent from my LG-H850 using Tapatalk
