    Yes. I installed a new system at our factory three weeks ago. See screenshots. I am making 55KW a day on the newest 8KW Deye Hybrid with a Volta Stage 4.

    Solarman dongle and the solarman cloud does allow for remote control - its clunky but it works.

    As per the title, will this installation pass inspection and is it allowed by SANS 10142?
    This is the workmanship that I am getting at my newly built house... Obviously I am not happy with it.

    Induna got a reaction from Flipper in New Sunsynk datalogger history missing   
    Hi, no I have not been able to recover it. I have sent Sunsynk numerous emails (to their CN support email address) and made a number of calls to the UK support centre (you are redirected there when you call the RSA number), but to no avail. I explained the situation to them in detail, via email and phone calls, and eventually I gave up. 
    Sunsynk is still my inverter of choice, and I have installed a number of them and recommend it to everyone, but Sunsynk really need to start focusing on customer service.

    not true. At 50% the battery is at 52.2V, so at 150A it can still supply 7830W. At 20% (which is the AM10 limit for 80%DOD) it can still supply 7680W at 150A.

    OK, so I got feedback from Hubble, and it is not good. Just for reference, this is what the AM10 specs says, as well as the specs advertised on Segen's website:
    From Hubble:
    Rated Capacity (5HR): 200Ah 
    Nominal Voltage: 51.2V 
    Design Capacity: 10KWH 
    Equalized Charge Voltage: 55.2V 
    Max. Continuous Charging Current: 150A 
    Max. Continuous Discharging Current: 150A 
     
    From Segen:
    Weight:
    99 kg
    Battery Type:
    Lithium Ion
    Nominal Energy:
    10240 Wh
    Depth of discharge:
    100.00 %
    Voltage:
    48 V
    Continuous Discharge Rate (Normal Use):
    7680 W
    Maximum Discharge Rate (5 Minutes):
    7680 W
    Surge Discharge Rate (15 Seconds):
    7680 W
    Maximum Charge Rate (5 Minutes):
    7680 W
     
    Hubble now have confirmed that the battery cannot supply 150A continuous and can only do 112A (0,75C). Although their datasheet explicitly states MAX CONTINUOUS CURRENT 150A, this is a lie and now I have a customer who cannot use the full potential (or even close) of his backup system.
    This is false advertising and sell batteries which cannot meet their published specs. Also, Segen states 100% DOD but in the Hubble manual it says only 80% DOD, so which one is it?
    Be aware.

    Induna got a reaction from Leetpro in City of Cape Town - Feeding Back into the Grid   
    During the load shedding this past weeks, my power has mostly been off 08h00-10h30 and in the afternoon either 12h00-14h30 or 14h00-16h30. So this means that they do have shortages during the daytime as well. Residential solar PV may not help after hours, but there is definitely a shortage during sun hours as well.

    Our govt is missing a huge opportunity. We are faced with increased load shedding. Normal people, like us, can contribute immensely if they just change policies to make it easy and effortless to register a solar system and allow feedback to the grid. Instead of them spending billions to build new power stations (which they still have to do btw) and waiting 10-15 years for full production, domestic solar systems are already online and ready to feed-in to the grid.
    There are 1000's of installations that are not permitted to feed-in. Look at the US for instance, they get govt rebate of up to 30% of their cost if they install a system and it is signed off. And then on top of it a lot of power companies give them a 1:1 tariff, meaning whatever they feed-in they can use again.
    I saw that Dear South Africa sent an email comms which indicates that the govt is exploring urgent ways of easing load shedding. Well, the solution is already at their disposal... Just make it easy for people to register their systems and feed-in and GIVE INCENTIVES to those that do...
    Our municipality has been "busy" drafting PV regulations for the past 10 years and still nothing on the table, but we have some of the most expensive electricity in the region... Govt policies are full of red tape which put a spanner in the wheels of progress.

    No, the smaller the depth of discharge is the less "wear" is on the battery. So a 4% cycle will not have a big effect on the normal lifespan of the battery.

    Induna got a reaction from JpPaulKruger in SunSynk 8.8kw. External mounting.   
    My take on it. According to the Sunsynk spec sheet: (quote)
    Operating Temperature Range (℃) -25~60°C, >45°C Derating
    So if fitted into a weatherproof enclosure, and operating within the design specification, I can see no reason why the warrantee should not be honored. 
    Also, the Sunsynk is IP65 rated (if all the glands seal properly) so dust and moisture intrusion is not an issue.

    Induna got a reaction from Yellow Measure in Battery circuit breaker trip   
    i am having the same issue. I have a Sunsynk 5.5kW with 2x5,1kW batteries. I have a 125A DC breaker installed on the battery feed and it also trips intermittently. There is no way my batteries can discharge more than 125A, as I have set the max power discharge from the battery, so worse case it would be around 104A when the battery voltage is really low and I use all of the 5kW (which I do not even come close to). The most I have seen was around 60-70A. Obviously the logger does not show any detail as it only updates every so often.
    Seems like breakers are problematic on DC circuits and I am also considering replacing the battery breaker with slow blow fuses.
    I am curious to hear other's that experienced the same and what their fix were.

    Induna got a reaction from Yellow Measure in 8kw sunsynk new installation   
    As Keith from Sunsynk always says, its not the current that kills the inverter (MPPTs) but rather the voltage. If your panels produce more current than the MPPTs are rated for, it is no issue, as the MPPT will limit the current to its design spec, but you will be wasting as your array will never be fully utilized. Also, 18A is per MPPT, and the Sunsynk 8kW has 2 MPPTs. 18A per MPPT is a lot and I don't think you will easily find a panel that produces that much current. 
    The way I went about was to select panels that has a current close to what the MPPTs are rated for, and then I selected the number of panels per array to achieve the highest SAFE voltage (Voc) allowable by the MPPTs. Lastly, I selected the wattage per panel (depending on my available roof space, etc) to achieve the required kW as calculated by my usage.
