Remember CoCT's limitation of feeding back to a max of 25% of the municipal breaker i.e. for a 50A, 3kW is max

Bump ... R300

R400

Item: Age: 3 years +- Price: R500 Payment Method Accepted: EFT/Cash Warranty: None Packaging: Boxed (not original) Condition: Barely used, my inverter works perfectly on WiFi sitting next to the AP Location: Cape Town Reason: No use, came with the inverter as a spare Shipping: Pudo locker Collection: Cape Town Link: https://en.goodwe.com/lan-module

Had my 3kw panels for almost 10 years and have paid for themselves yeeaaarrs ago! I would make the same decision again every time 😎. Now going to upgrade by adding more panels. For me Solar = roi battery = load shedding convenience

Bump ... now R3000

Bump ... now R3500

Impressive and solid plan! Up until this post, my (terrible) memory doesn't recall seeing anyone propose that it's worth it to feedback. Not at this scale What have you calculated as the meter fees with the new discounted model, and the payback return per kW? Would be cool to see that napkin

Can you share your requirement? That can help with comments on the solution design. What on earth do you need 32 x 560s for, with only a 14kw battery?

After many years of loyal service, it's time to let my Imeon go after upgrading to a Goodwe. We had this managing 3kw of panels and 2 US3000 and it delivered superbly. Included are the battery and grid connectors along with the IMA box needed for remote connectivity and management. The IMA alone costed R5k 4 years ago .

For those struggling, I managed to get a workaround going. From what I've read HA contends with SEMS for the API. So all I did was point DNS on the inverter to a null IP and the HA retrieve works consistently even at 30s intervals I'm fine with SEMS not working 😉

So I started the HA integration. First challenge is that the power flow card works, but updates intermittently. I've tried using Goodwe default polling or with an automation using UI or editing the yaml, both setting the polling to 60secs ... all 3 results in the intermittent data being updated and the debug logs below. Any ideas would be appreciated as this is way over my pay grade I'm on a LAN module running latest HA and 2525J 2024-03-01 08:55:30.217 DEBUG (MainThread) [goodwe.protocol] Sending: aa55c07f0106000245 2024-03-01 08:55:30.590 DEBUG (MainThread) [goodwe.protocol] Response has unexpected length: 61, expected 149. 2024-03-01 08:55:30.591 DEBUG (MainThread) [goodwe.protocol] Received invalid response: aa557fc001868c0fd5000d01000000000001f00001005001070013004a004a00002c002c6003000001088f001b0040139301088f002d000a1393010201 2024-03-01 08:55:30.591 DEBUG (MainThread) [goodwe.protocol] Sending: aa55c07f0106000245 -

switching topics to automation. Has anyone managed to integrate a Goodwe with Home Assistant with a config I can copy leverage 😊 ? I now have the GW5048D-ES installed (Yay!) along with 2.4kw of PV and 2 US3000 Pylons. I'm thinking of a setup where batteries are discharged every night to 20%, and charged the next day via PV (irrespective to 100 on clear or 50% on cloudy) HA pulls the ESP data If LS is forecasted in next hour + PV FC is below 1.5Kw + battery is below 40%, THEN charge the battery from the grid only to 40%. This should cover the LS window and should be the only time batteries are charged from the grid. It should also cover day and night scenarios Anyone manage to get this right or a better solution?

Thanks folk for the guidance ... the decision is clear!

Firstly I had to google GIMF ... the irony 😜 Thanks folk. So in summary, both @Bobster. and I have a 11a MPPT threshold. We can use the newer panels but won't be able to reach optimum performance by ~20% with clipping? That sucks long term when I'd want to replace an existing old string in 3-4 years, as 11A ones will likely be extinct. Have to reconsider the good deal on the GW5048D-ES, or suck it up and buy the newer GW5000-ES20 instead ... decisions

@Bobster. can you pls help explain your sentence to a newbie like me ... Back to the original point: The spec sheets specify a current limit, not a power limit. The ES will allow 14A per MPPT, whilst the EM allows only 11A. I'm buying a GW5048D-ES (model below) and just want to make sure it supports the latest panels which all seem >11A I understand there are 2 versions (old supports 11 and new 14). Is this one capped at 11 and does that mean I can't buy any of the latest panels?

Greetings Anyone have one of these for sale? My Imeon 3.6 is still chugging along nicely after 8 years and I'm wanting to try some feeding back with zero exporting to the grid. Item Wanted: Imeon Smart meter single phase Packaging Essential: no, but hopefully includes the cable Desired Age: n/a Location: Cape Town Willing to accept a shipped item: yes Ballpark/Budget Amount: R500-1000. Depending on condition and cable

Both the spec sheet and the salesman in the webinar above quotes (video 9mins and 25mins in) 10kw peak with grid. The 10kw peak for 10 sec is without grid. Unless I'm misunderstanding

Well, the 5kw (Goodwe GW5000-ES20) is actually a 10kw peak with grid, and 5kw without .... according to the specs and video above. I'm struggling to understand why this is not flying as the no1 seller - it's such a great spec sheet!? Has anyone installed one yet?

Huzit - did you decide to go for this model? I'm really interested for the same reason of using the excess energy

around 90k, incl.

Greetings all Anyone managed to play with or install one of these what looks like a PowerWall competitor? https://www.eaton.com/gb/en-gb/catalog/energy-storage/xstorage-home.html They seem so simple and available in SA with reasonable pricing. Model we're looking at is 6KWH lithium/6KW peak Any thoughts perhaps?

Thanks so much for the guidance everyone .... really appreciated 🙏

Yup, can see why. Cool beans Another question does SMA integrate as well as the Fronius with the MP GX, allowing a single Victron web interface for both data?

Thank you, that makes perfect sense! We have no issue that PV is down when grid is down as the Pylon covers the essentials. So it looks like Option #1 is the best design (for us) Why is it so rarely deployed if it offers higher solar consumption and is slightly cheaper? Is it because Grid down = PV down?
