Hello JDSym. Im interested if still available. Thanks

Hello. I'm interested if still available.

Thanks Kalito for information on Solar MD relays. In trying to understand the power limits in the relay as it a dry contact rated at 3A @250V or 1.5 KW and ... the Geyser element and air conditioner is more than this so surely its overloading the relay?

I am exporing a small-medium scale industrial PV system (< 1 MWp) on available agricultural land. A 1 ha lowland area is available at Sandberg Fynbos Reserve- a 600 ha private nature reserve in Overberg, Western Cape. The property has overhead Eskom power lines (22 kVA or 33 KVA ? and rights over the land on way-leave basis) and then the thinner 11 KVA line branches off this to the main DB at the farmhouse. The 1 ha land has a potential for up to 700 KWp solar PV on a “Agri-PV” land use model. It is envisaged that the shading from ground-mount solar PV could be used for a nursery for plant propogation (see attached pic). The Solar PV will be grid-tied with Eskom feed-in and most of the revenue of will be from electricity sales to Eskom, although Sandberg Fynbos Reserve has 6 households that can also be fed from teh sola system and direct customers. Sandberg Fynbos Reserve entrance is on the R43, located 34°34'30.01"S, 19°41'35.65"E. The proposed 1 ha Agri_PV: 34°34'39.55"S, 19°41'31.12"E What is the opportunity and feasibility of this project? Does it depend on the local grid capacity and lines? If so, how can this be assessed? I have emailed Eskom to try clarify the max feed in that will be considered (no reponse) and tried to gather information from Eskom web-site and SSEG legislation. I have used tools to estimate the solar potential at this location ie 700 KWp will generate 970 035 KWh per annum In terms of legislation, I do see that solar <100 KVA does *not* require application to NERSA so this should be a much simpler process? https://www.eskom.co.za/distribution/wp-content/uploads/2021/09/SSEG-process-fact-sheet.final_.pdf https://re.jrc.ec.europa.eu/pvg_tools/en/tooand 700KWp solar ls.html#PVP https://www.ise.fraunhofer.de/content/dam/ise/en/documents/publications/studies/APV-Guideline.pdf This opportunity could be self-financed or developed by an outside business who leases land at nominal fee and provides the energy service to Sandberg residents. Any insight and oppinions will be very valuable. Thanks!

Thanks Tinuva- the remote upgrade worked exceptionally well. The documentation still indicates accessing the usb port and doing a manual upgrade and my installer did not do this. I confirm that creating account and submitting a ticket on support.goodwe was simple. I registered as owner, created a non-urgent ticket (more info needed, everything working OK)...and I was astounded that I received an email reply in 4 minute indicating firware will be pushed and inverter will re-boot. 10 minutes later all done. Fantastic service. Firmware 1212114/0 upgraded to 1222215/0. I was having some intermittent Wifi disconnect issues so that data was not being logged to the SEMS cloud and hopefully this will resolve it (the SEMS profile looked scary as the drop in data recording made it appear on SEMS that the battery totally discharge to 0%). Will report back if there are any remianing problems, otherwise all is working well and Im very pleased that there is no fan noise from the inverter as its near my office. My setup is : 6.48KWp Solar PV (540Wx12 in east-west array), 4.6KW Goodwe GW 5048D-ES, 7.4KWh SolarMD battery)

...they seems to be compatible with many others. Will using "default lithium" setting work with Luxpower inverters?

Is Hubble battery (AM-2) compatible with Luxpower inverters?

Thanks! Much appreciated. I wil make contact.

Great! LXP sytem will work well to extend the UPS capacbility and store excess PV-generated electricity. Since the LXP 5K hybrid can take lost DC oversizing with 8KW solar, but its backup is limited to 5KW (EPS+ solar) and so adding a AC3600 storage invterter will add additional UPS and double the charging ability (ca from 100A to 200A). Great for my outbuildings with cottage so they can have backup during loadshedding. The battery compatibility of LXP looks excellent and Im keep to use 2x Hubble AM-2 rate at 1C or 100A)- one for the LXP AC2600 and one for the LXP 5K hygrid I presume this is OK according to NRS097 (ie the AC3600 storage invterter is a UPS and not considered a generator? I also noted Luxpower is availabe at Aspergo, but I do need an installer. Please can you post/PM and recomend one.? I am in Stellnebosch, Western Cape and wish to do a grid tied zero feed in install. Thanks very much

Thanks!. A further question: Can the EPS batery backup of the LXP5K system be increased by adding the LXP ACS 3600 ac couped inverter? I am thinking if the batteries are seprate and loads are split thsi is possible ( I realise that teh putputs cannot be couped, or parralleled) ie one EPS for house using LXP5K hybrid and one EPS for cottage using LXP3600ACS on same property. In this way solar PV can charge both batteries in daytime and in Eskom outage or night the EPS of the two systems supply the respective loads as needed (ie when my peak demands are 6-7KW)?

Thanks. To clarify, understand EPS and limits of the inverter output regarding ESSENTIAL loads that you have mentioned. However, for the NON-ESSENTIAL loads connected to the grid side, I presume that they can get the power from both inverter and grid ie if I have a non-essential load of 7KW will it get 5KW from PV inverter and 2KW from grid?

Hello. The battery output or EPS is understandably limited to 5KW. However, you mentioned that the LXP 5k has "5kw max continuous output on EPS with GRID". Does this mean that the AC load is limited to 5KW or does the inverter have passthrough capability so that the max demand of the on-grid loads can be achieved (of course up to the breaker limit on the the DB)?

Thanks very much as it now makes sense when you said: "its the same port. You EITHER use it as a generator input OR microinverter input OR smart load which is an output. " To an unexperience eye the circuit diagrams does not seem like load and gen is the same port. (Sunsynk 8k manual)

That makes sense...but: The generator port is not only an input- thats why its called auxillary (aux). Aux port can be used for smart loads (loads only on when battery full or at specific percentage). Then I also noted that AC coupling to the batttery ouput/UPS is possible so this port is also not only and output!. However, using the UPS output as input for microinverter somehow disdables use of the aux port. Hence my confusion!...

Thanks Achmat for confirming its not possible to do both! Looking at info I still dont understand why the genertor port (aux port as you better call it) cant be used for the Smart load function and the AC coupling of microinverter connected on the battery UPS output (since its bi-directional inverter I believe). Looks like you cant have both as shown in the manual diagrams of settings, but is this a software or hardware limitation?
