I've run into a bit of a deadend with an issue I'm having with my Sigenstor settings.
I have 15kW solar PV feeding a 48kWh 3PH Sigenstor battery with a 25kW inverter. My power plan has a 3 hour period for free gris imports (11am-2pm) capped at 24kWh. I have set up a time-based Operational Mode between 11:00-14:00 with maximum power for importing from grid set to 8kW and maximum power for charging battery set to 8kW. However, today I noticed that the solar PV was generating at around 9kW, Load was around 6kW and the battery was charging at about 17kW with 14kW draw from the grid, meaning that the 24kWh free energy cap was breached.
It looks like my settings are applying the full 8kW allowable from the grid to charging the battery plus all of the power generated from the solar PV with the load being fed from the grid. What I was expecting was that the load would be fed from the solar PV with excess charging the battery along with 8kW from the grid charging the battery – no grid power being used for the load unless the power from the solar fell below the load. The Solar Producing Source Priority is set to Basic Load > Sigen Battery > Grid.
It looks like I should be able to set a Grid Import Power Limit but this option is disabled (Grid Settings are either locked or disabled, with the exception of Block Battery Grid Export). I'm also not sure whether I can just set this limit to 8kW to apply only during this 11:00-14:00 period. I've read about custom modes being able to unlock some of the grid settings but I can't see anywhere to set any custom modes.
What am I missing here? All I want is for the system to draw from the grid to prioritise charging the battery at up to 8kW and direct nothing for the load, unless there is insufficient solar to cover the load.
Also, just starting today, the Energy Statistics, Sankey Diagram, Power Metrics Chart and Battery SOC Chart have all started lagging by over 2 hours in both the app and on the web interface. All software is up to date.
Has anyone had an issue with the MySigen app Power Metrics and Battery SOC plots lagging by a significant period? My app is currently showing ‘latest’ data from about 90 minutes ago rather than 5-10 minutes as usual. As best I can tell it started last night, so less than 24h ago. All time settings seem correct?
Edit: All stats outside of the graphs seem to be current, so not sure it is a data connectivity issue.
Hi all
(Crude wiring diagram for context)
Looking at getting a Sigenergy solar/battery setup on my property
We have the main meterbox on a pole in the middle of our property, and 4 buildings connected to individual 63A circuits that then go to each buildings respective subpanel.
We also have a diesel generator connected to a changeover isolator switch in the main meterbox on the pole which lets us flick between mains or generator for when we have a power outage.
We are looking at 18.5-24kW of solar on the main house, with a 48kW battery (potentially over 2x inverters w/ 3 banks per inverter). Hoping to have the battery service the entire property and not just the main house.
I know the inverters and gateway are limited to 12kW capacity - but we can consume up to 20kW of power at any given time. Unfortunately we are only single phase and our grid does not support a 3 phase upgrade.
I understand the parallel inverters which allows this to go up to 24kW throughput to make full use of the solar panels to charge the battery more efficiently, but I'm confused with the gateway.
Installer is saying we can have the batteries/inverter on the main house, and the gateway at the pole (and somehow 'trick' the gateway to use the main house's circut to feed the battery into the gateway)
the gateway is still only 12kW limited though, so what happens if we are consuming 20kW?
Assuming 12kW through the gateway from the battery, and 8 from the grid? But what about during a power outage, or when the generator is active?
I would assume that we could wire up the gateway from the output of the generator changeover isolator switch so it would think the generator is just a standard 'mains' input so it can make use of the higher throughput vs hooking it up to the backup input?
I thought I saw somewhere there was an upgraded SP gateway (HomePro SP-F) that could support 100A mains and multiple inverter inputs, but I can't find much info about it on whether it is still limited to 12kW total or not.
Any advice or feedback welcome
Thanks in advance!
I'm in S.A. and had my SigenStor system installed last Friday. My smart meter won't be installed until June 5th.
If I manually tell my system to discharge from the battery to the grid it says it is discharging and the battery SOC decreases as one would expect. But do I run the risk that this will count as consumption rather than discharge given I don't currently have a smart meter installed?
What do I do if my battery is full but my solar is still producing and starts exporting power?
Anyone want to send me there account number or globird address so I can give them $50 refferal. I signed up forgot about referral but can still get it if I have account number or address
I'm in Canberra (15kw export limit) and recently experienced our first grid event on Origin's Loop VPP. During the event, inverter capacity was limited to 5kw and PV output went to zero! Was a midday on a sunny day. Worse still, if house load went to say 6kw, 5kw came from battery and 1kw came from GRID 😞
Pic in comments from Sig app shows some value which might be the issue, though it's not adjustable. This seems to be the setting from Origin for that event? Origin swear 'they only instruct the battery to discharge and not change any other settings'.
Any thoughts?
I'm having issues with my car not charging, what i'm getting is the car trying to inisalise the charge. I hear the car locking and unlocking the plug and you hear the charger contactor going on and off.
I've had the car checked by Audi and they are reporting that there is no issue and everything was working properly.
Has anyone else had any issues similar to this and if so, what was the fix?
Hi Guys,
need some guidance,
have a two-phase site with 480 L-L voltage so our only option is to install two single-phase inverters with two single-phase gateways and commission the systems independently. My concern is,
do both systems need to know the total import and export of the main? So do we need to have a 3-phase power sensor additionally, or leave it as it is without additional power sensors?
Hi guys, from SA with ❤️! I'm looking at Sigenergy battery 40+ Kwh 3 phase with a DC charger for my home. How much will it cost?
I haven’t seen it mentioned, so I thought I’d share.
I recently asked my battery installer for a quote on the AC charger, thinking the cost of the DC would be prohibitive. They quoted $3,100, which seems very high. Their explanation was that because my switchboard was on the far side of the house from the garage, that cabling added a significant amount.
They suggested the 12kW DC charger instead, seeing as my battery is in the garage and the cost had recently dropped about 40%. They quoted $4K (installed), which would be a no-brainer for me compared to the AC option.
I also asked for a quote on the 25kW charger, which was $5,500. Also tempting.
I am wondering if the prices may come down further. Also conscious that the energy crisis could push prices up in the medium term.
Keen to hear anyone else’s insights.
ETA: we’ve already had our battery installed. I’m sure prices are generally better if you get the charger installed along with the battery.
My question is similar to some of the other recent posts but didn't want to hijack them, I have 15kw solar on a 15kw 3ph inverter, gateway and 16kwh of batteries on my house. I want to add more panels with a standalone Sig inverter and have a couple of options but unsure of what the capabilities and limitations of the Sig system are:
Detached garage with a 20a 3ph supply, can I add another 8-10kw of solar and 3ph Sig inverter using the existing supply instead of a dedicated cable back to the gateway? Dedicated ethernet is available.
Sleepout with 2ph supply cable from gateway but only 1ph used, can I run a single phase inverter on the unused phase but sharing the neutral? I assume the 3ph house inverter will work to balance out the phase loading based on the grid CTs? Only shared ethernet available from here but wifi to both.
Thanks
So we’ve just lost NBN and I wanted to check the Sigenstor to see the battery level. Im on the same Wireless network but the app is showing stale data and nothing for the current usage and battery level.
Surely I should be able to direct connect to the system without internet?
Have installed sigenergy + intelligent go tariff for EV. Using sig AI which is doing well - with the exception of handling the extra octopus intelligent slots
As i currently set the tariff plan in sigen manually, and there's no integration for this intelligent tariff, for the hours (2330-530 offpeak) any extra window put in by octopus will not register - meaning when the charger pulls electric then, the system will dump the battery to power it.
I've managed to get all the tariffs into home assistant, including when octopus adds new windows - however cant see how i can automate the writing of the new windows into the sigen app. Anyone dealt with this?
Looking for someone who has Shelly installed to control hot water tank. We have battery but no gateway so our option to control hot water tank is either contactor with timer or Shelly. I have asked our installers for Shelly but they now saying they will not install it as there are issues with it and they can only do timer. Anyone has issues with Shelly?
Currently have solar and battery on my house! Sig gateway with 10kw inverter + 48kw battery.
I’m looking to add solar on my garage. With another sig inverter (0 export) and maybe 1x8kw battery in the garage. I mainly want it for the extra solar as my house roof is full already
Only this is there is only 1 conduit buried between house and garage. Can’t get a second cable to the garage and back to the gateway. Can I put the inverter on the sub board in the garage and get it to communicate with the first inverter on the house?
Help me understand how my inverter imports more than 10kw when is powering the battery and the house, but won't do the same when the ev dc charger is connected. The evdc charger starts working to 10kw only when the battery is full, but can do 12.5kw when battery boost is enabled.
Any way I can have both maxed out at the same time? 10kw going to the battery and 12.5kw (or the maximum per single phase) to the evdc.
My setup:
10kw inverter
32kw battery
12.5kw evdc
10kw solar
Have 40kw battery and a 12.5kw DC charger system and thought I was good with the AI system to ensure I have battery for peak morning/afternoon times and also some charge in my car.
Turns out the AI is all but useless, over had it running a few months so assume that would be enough time for it to adjust its settings.
So to find a better option I found Predbat for Home Assistant and wondered if anyone else is running it to control the battery instead of Sigen AI.
I have it in monitor mode at the moment with some additional sensors before I allow it to control my system. My plan is to let it monitor and see if it is smarter than the Sig AI.
Anyone able to comment on Predbat and if it is better than the Sig AI before I custom create something that will ensure I'm not paying peak rates for no reason.
