Questions



questions Brian on 15/01/2020
Question: 

Can this be connected to three phase ?

Answer: 

Hi Brian. No, this is a single phase solution only.

questions Chris on 10/12/2019
Question: 

1. I am confused a little. In your Key Features write-up, you say the Battery Capacity is 11.4 KW. Then in your SPECS write-up, you say the Battery Capacity is 5.7KW. I am hoping that it is indeed 11.4 KW. That's a big difference. So which is correct? 2. If Standalone acting as a backup to AC power, (no Panels charging) how does Smile5 know when to charge itself from the Grid? I would think of ordering one as a backup in the first instance and using it to run a few appliances. Then as soon as possible & when cash avail installing panels to complete the system. 3. Is there an owners manual or technical manual avail for me to learn about this Inverter/Battery system. 4. Is there an installer in Somerset West who has experience with this system. Thank you Chris

Answer: 

Hi Chris,
1) the system has 2 x 5.7kWh batteries , so in total it's 11.4kWh
2) this can be programmed into the system
3) yes, get hold of us via email and we can share it
4) We have installers in Cape Town that can help

questions Jacques on 10/12/2019
Question: 

Can you run it without solar panels, ie, charge with grid and use as backup during load shedding?

Answer: 

Hi Jacques, yes you can.

questions Hein on 26/11/2019
Question: 

1. If using panels like Canadian Solar CS3W-400 (Voc= 47.2, Vmp=38.7), what is the minimum number of panels per string that will reliably start the MPPT? 2. Will this minimum still mean that I will operate at maximum power point? 3. The battery is specified as 0.5C, so while in grid failure I understand that I will be limited to around 2.7kW on the essential loads. However, while the grid is active, can I supply the full 5kW to the essential loads? 4. I understand that if the battery inverter trips while the grid is off, the system cannot be reset until grid power returns. Is this true, and if so why? 5. Can you confirm that while the grid is active, the battery can supply the grid connected output too, and not only the essential loads? How much control do I have over the power (W) supplied to either the grid-connected vs essential load outputs?

Answer: 

Hi Hein, in answer to your questions:
1) The MPPT operates between 125V and 550V, therefore you would need 4 of these panels to operate it reliably.
2) Yes
3) Correct, on a per battery basis, but the system comes with 2 batteries, each capable of 0.5C, thus you can draw the full inverter capacity power from the system.
4) This only applies to the grid-tie functionality, not the backup output. This is because grid tie needs to sync its voltage and frequency to the grid supply.
5) yes it can, this is the part that won't work without the grid supply. The system will supply the essential loads and battery first. Any excess can be directed to the grid. It is also possible to supply the household grid, yet prevent the system from exporting across the meter.

questions Martin Coetzee on 12/11/2019
Question: 

Hi, can I start with 8 x 350W Panels on one MPPT and one battery ( 5 kWh ?) with the idea of upgrading later?

Answer: 

Hi Martin, yes you can. The only thing to consider is that the Alpha batteries operate at 0.5c, which means that when operating on battery power alone, you will only be able to get a peak power draw of 2.5kW off a single battery

questions Dave on 17/08/2019
Question: 

Hi. From what I understand in the previous Q&A below, this is Alpha-ESS Smile5 Energy Storage system is Grid-Tied? Once the batteries are charged, excess power is sent back into the grid? Should I run out of battery power during the evening, the Smile5 will draw current from the grid? Thanking you kindly Dave

Answer: 

Hi Dave, that is correct, except the system will first charge your batteries and run your backup loads (you can decide the order in which it does this), and only then will it feed excess power to the rest of your household grid. It has further functionality built-in that then allows you to decide whether you want to exports any left over power backwards through the meter or not.

questions Eugene on 04/08/2019
Question: 

Hi We use 1,200 to 1,400 kwh per month and want to install a system that enables us to run 100% on solar, but still remain grid-tied. We live in Pretoria East and our roof is not optimal for panels (we would need to add more panels, one set East facing, and the 2nd West facing) to ensure that we can generate enough to support our night time consumption. In total, we have space for about 18 panels. Can you recommend a panel that would meet our requirement? How many Lithium batteries would we need?

Answer: 

Hi Eugene, you will need two of these systems to do that. You need approximately 10kW of panels to produce 1400 Units per month. The battery requirement will depend on your day/night energy split, but the batteries supplied in the system will generally suffice.

questions Dries on 25/07/2019
Question: 

Can this be used off grid?

Answer: 

Hi Dries. It can yes, but a lot of the cost of the unit applies to the grid tie functionality which you would then not be utilising.

questions Jimmy on 24/07/2019
Question: 

Good day. If I have 18 X 325Watt Panels @ VoC 46.35 and want to split the array to have 9 panels Facing East and 9 panels facing West how would the panels get grouped in series or parallel to connect to the Alpha Ess Smile5? Where could I find a Solar Panel Wiring Diagram for this Unit?

Answer: 

Hi Jimmy, it's very easy. A row of 9 panels in series for each side of the roof. each row of panels will connect to one of the Alphas 2 MPPT's.

questions Jimmy on 24/07/2019
Question: 

How would I wire the system so that only essential appliances receive power from the battery in the event of a power outage but excess produced power from solar can still be fully utilized during the day by other appliances like a geyser when the batteries are fully charged?

Answer: 

Hi Jimmy. The Alpha ESS has this functionality out of the box. The circuits you want protected during power outages are connected to the backup output of the Alpha. Any excess solar power produced (after the backup loads are being powered and the batteries charged) will flow onto the rest of your household grid (This is the grid tie portion of the functionality).

questions Jac on 09/07/2019
Question: 

Good day Can the batteries be replaced after 10 years independently of the built-in inverter? Regards Jac

Answer: 

Hi Jac, they certainly can, although we would hope they last longer than the guarantee period.

questions Ganesh Prasad on 02/07/2019
Question: 

I have an Alpha-ESS Storion SMILE5 system - 17 x LonGi panels of 315 W, producing 5.3 kW, inverter and two batteries with a combined capacity of 11.4 kWh. But this only covers me for 2/3 of my power requirement. The remaining 1/3 I have to draw from the grid. With the same inverter, can I add more panels and more batteries? I'm guessing I need 6 more panels and one more battery, but what is the maximum expansion I can get with the current inverter?

Answer: 

Hi Ganesh, yes you can add more panels. You can theoretically put 24 panels onto the system but you will experience some clipping at peak production. Adding more batteries is not a problem.

questions Rory on 17/05/2019
Question: 

Morning Does this system work as a hybrid inverter, in other words, will it use a combination of grid, solar and batteries depending on how it’s programmed. Or would I be better off with your 6kw solar power solution and a Goodwe hybrid inverter

Answer: 

Hi Rory. It does indeed. It has the same functionality as the Goodwe, only in an attractive package and is better value if you're looking for a decent amount of storage.
