Recommended Posts

Hi all 

 

Quick one has anybody had any experience with the luxpower products specifically the 5kw hybrid, I'm looking to purchase one and would appreciate any feedback from installers,users/owners.

 

Product marketed as a hybrid in inverter that is able to blend from all 3 sources PV,Battery and grid. Specs attached 

 

Thanks

All I can say is it does not look like the usual common as garden weeds rebadged Voltronic. It has a high voltage DC input on the PV side, and the high efficiency numbers (which will be boosted as much as possible by the marketing team, but still has to be at least theoretically possible) suggests this is a high frequency inverter, probably on par with a Goodwe (or thereabouts).

Other than that... certainly not a name we hear often.

Thanks for the feedback,research implies that this brand is huge in the UK and growing. Granted the UK isn't the SA, but the monitoring software looks very user friendly and the fact that it does remote monitoring and maintenance via app and pc is amazing. Pitty not many locals have experience with it would have liked to hear from them before pulling the trigger on one

Just a word of caution, just know what you might be getting yourself into, if the product support is bad (or maybe even non existent)

Then you could find yourself beholden to help from people on forums willing to help you, or in extreme cases even a couple of friendly Aussies providing you with firmware updates because the manufacturer could not care less.

From what I can see Luxpower is supported by Aspergo. They are also the importers of Dyness batteries into SA and have dealth with Andy the owner and has been very helpful in doing upgrades to my batteries when we had issues. If my Growatt ever blows its last smoke I will definitely consider Aspergo's offerings.

Good afternoon, thanks for the mention TSA.

Our website is busy updating and there will be a registration portal for resellers and installers.

As for the Luxpower brand, we are the official importers and stockists. We are based in Durban and carry the following:

LXP5K - 5kw full hybrid.

  • Stainless chassis, fully sealed. IP65
  • NO cooling fan, but has massive heatsink which pretty much covers the full length of the inverter.
  • Dual MPPT
  • Available in Standard and Parallel model (up to 10/phase)
  • Remote monitoring on OEM platform, with remote maintenance and settings as well.
  • At the moment the output is as follows:
  • 5kw max continuous output on EPS with GRID
  • 5kw max continuous output with solar and battery.
  • 3,6kw max continuous output on battery only - We are rolling out an update next week to 4kw with 4,5kw for 100sec on battery
  • Seamless EPS switching
  • 5 year warranty

The key thing to note is that the user interface on the web server gives the user a large range of settings, most importantly remote maintenance.

We have over 100 units installed throughout SA, either with AGM batteries or Dyness lithium. The Dyness BMS works very well with Luxpower and is by far our most stable platform. 

To maximise the EPS output of 4kw, we pair it with 3 x B4850 or the Powerbox F7.5 (7,2kwh) which will then comfortably deliver the loads on battery only.

We're launching our OFF-GRID inverter next month.

  • 5kw off-grid.
  • 4kw pv - dual mppt. Possibly 4 pv inputs 145v DC (we're discussing a few options)
  • dual power input - GRID and Generator
  • EPS out
  • Fan cooled
  • Parallel up to 10 units/phase
  • 2 year warranty

We also have a 3,6kw AC coupled, either for retro fitting to grid tied solar or standalone UPS. Also parallel model available.

No cooling fan - silent like a starlit night in the desert.

I can attest to be above by (Tsa), after numerous back and forth mails and watsapp messages (some late evening)with Andy the owner of aspergo energy. I'm pretty confident in he's company and product offerings. I initially just to wanted to buy lithium batteries from aspergo and ended up  buying batteries and the luxpower inverter from a guy (Andy) who took the better half of an hour to video call me to show me the products I enquired about, he unboxed and fully connected ,set inverter up with batteries adjust dip switches and all of that (I'm clueless on this), took the time to explain and advise on product and limitations, pros and cons you name it,packaged it all back up and ready to ship. All of this done before I even paid a cent to this man,that is service on another level and a business I will gladly support again and again

 

Order placed and paid for currently waiting on delivery. Will advise again when I'm up and running.

Aspergo gives great service we installed 3 of those units in parallel with 8 dyness 2.4 KW Batteries and a 3KW wind turbine and about 6.5 KW solar panels with a diesel generator as backup and thus far the client is very happy this is a complete off grid setup. He has not yet needed to start the generator.

5kw max continuous output on EPS with 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)?

Good afternoon, and thank you for your enquiry. 5kw max continuous output on EPS can be achieved with (SOLAR + BATTERY - in an off-grid situation) or (GRID + SOLAR - in an on-grid situation) .

Our inverter does not have a secondary AC output, so only the loads connected via the 'ESSENTIAL Circuits' will be supplied to  max of 5kw in the above scenario. Excess solar is fed back through the AC input to the Non essential side of the loads, and export is limited by a CT clamped to the L on incoming feed between meter and meter and Main CB.

Hope this answers your question.

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?

Yes that is correct. 

On the Luxpower you can fit up to 7200w of solar power, but only 5kw will be used for loads. The balance is used to charge batteries if charging hours are selected at higher solar yield times. 

The only time excess power is transferred to the non essential side is when the EPS loads <5kw and solar yield exceeds EPS loads.

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)?

Yes you can run 2 seperate systems. The nice thing about this is. :

1. The excess solar export when grid is on will be absorbed to charge the AC coupled unit, and

2. Both will be visible on one app. 

 

The other alternative is to buy our new Luxpower 5kw off-grid. 

1. True 5kw output on battery (make sure you fit big enough batteries, this boy punishes them) 

2. Fan cooled. Must be in an area where you're OK with fan cooling. 

3. 2 year warranty. 

4. This is the coolest part. It has a hybrid function where solar and grid share the load. 

5. Remote monitoring and maintenance. 

6. Price is R11'900.00 excl vat 

7. You can parallel up to 9 units per phase. 

8. By next week we'll have the REVOV battery on our options menu.

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

The 3600ACS does not require NRS certification, because it cannot generate nor export power. It does come with 2 CT clamps (1 to monitor grid and the other monitors the output of a grid tied solar inverter) it you want to retrofit it to a SMA Sunny Boy (for example). 

We have an installer based in Plettenbergbay who travels to Cape Town on occasion to do installations. 

You can mail me on [email protected] or call on 0825555077 and I'll share the info. 

I'll be in Cape Town from 24th to 29th April for a memorial and staying in Somerset West.

Yes it works well.

Select Pylon as your battery.

Make sure you have the correct CAN cable.

Use the HUbble CAN out.

Set the DIP switches on the battery.

How about Revov Li ion batteries?
