Tiron Posted January 14, 2020 Share Posted January 14, 2020 Good Day all. I installed 6 x 275w panels 2 x 3 panels in series then then connected in parallel to supply 100v to inverter. Started up the system and load distributed to supply AC to house and charging the battery. My problem is when battery was fully charged it stop the pv power and only ran on battery. When battery power was completed the system shut down. Can some one help me with the correct settings for synapse inverter 5k 48v Battery is a Pylontech Lithium Ion Battery US2000B Plus 48V 50A 2.4KWH, Quote Link to comment Share on other sites More sharing options...

Can you post a picture of the label on the side? If it is a clone, there may be no "correct" settings to make it work. 7 hours ago, Tiron said: Battery is a Pylontech Lithium Ion Battery US2000B Plus 48V 50A 2.4KWH, One PylonTech 2.4 kWh is very light for a 5 kVA inverter. You could only run it at half power for short bursts, quarter power continuously, and at quarter power it would only last some 24 minutes.

Tiron Posted January 14, 2020 Author Share Posted January 14, 2020 Battery ran for 4 hours then shut down. I do not have a big load on it. Please see photo if inverter. Quote Link to comment Share on other sites More sharing options...
Coulomb Posted January 14, 2020 Share Posted January 14, 2020 Ok, it actually looks legit. What is your value for setting 31, Solar power balance? It should be SbE, which used to be the default, but maybe it no longer is. I've never understood the purpose of this setting. Quote Link to comment Share on other sites More sharing options...
Tiron Posted January 15, 2020 Author Share Posted January 15, 2020 Hi Coulomb It is running and alternating between battery and solar. At 54v PV shut down and battery take over till 51v then Pv charge battery again. Can the inverter be set to use solar directly till solar power supply is to low then only use the battery.

That does sound like setting 31 (solar balance) is disabled. 4 minutes ago, Tiron said: Can the inverter be set to use solar directly till solar power supply is to low then only use the battery. These inverters never strictly speaking use solar "directly"; they use solar to charge the battery, and the battery charges the load. If there is enough solar power, the power more or less does power the load directly, because the output of the solar charger is at a slightly higher potential than the battery. So for all intents and purposes, as long as you have enough solar power for the load and losses, the solar powers the load. Towards the end of the day, as the solar power fades and slips below the loads, the battery starts contributing a little, then more, and eventually supplies the whole load by sundown. This is presumably what you want. Quote Link to comment Share on other sites More sharing options...

Jeffery Posted March 13, 2020 Share Posted March 13, 2020 Good day I’m currently at my client and I’ve installed 3x 5.0k+ in parallel (synapses inverter) but one inverter doesn’t change to Parallel and stayed on single it doesn’t link in parallel with others but the 2 others does link in parallel.. what can i do please?

It turns out that Axpert Kings (@Tiron, this is a King, right?) don't have setting 31, and furthermore it defaults to disabled. But you can set it back with PSPB1.

IMB Posted April 27, 2021 Share Posted April 27, 2021 Good day I installed a Synapse 5kw+ 48v inverter with 3 solar panels and 2 2.4kw Lithium 48v batteries. The panels do not change the batteries. The panels do indicate on the Inverter. What can be the problem? Thank you Quote Link to comment Share on other sites More sharing options...
Coulomb Posted April 28, 2021 Share Posted April 28, 2021 20 hours ago, IMB said: The panels do not change the batteries. The panels do indicate on the Inverter. What can be the problem? If the PV icon is present on the LC Display, it means that the SCC has power (from panels), is communicating with the DSP (inverter's processor), and is happy with the PV voltage (not too high or too low). At least, if the Synapses are genuine (not clones), and I'm 95% sure that recent models are. So then it could be settings, though you'd have to have very unusual settings to never see any charge current. Are you seeing non-zero PV power (INPUT, PV and W showing on a data page)? Is that power around 80% of nominal panel power near noon with no shade? If yes to both the above and there is no charging of the battery, it could just be that the loads exceed your panel power.

Logesh Posted November 8, 2021 Share Posted November 8, 2021 Hi all. I have exactly the same inverter. How do I set the inverter to run in bypass mode when utility is on but also charge the battery at the same time? Please note I do not have solar at the moment. Also I need it to switch to battery automatically when the utility goes off. Quote Link to comment Share on other sites More sharing options...

You want something like Uti output source priority (setting 01; it might be called something else, like USB), so that loads run off the utility when present. Then you just need to enable utility charging; that's setting 16, charger source priority or solar energy priority, depending on the model. Choose one of the settings with UCB in it (Utility is allowed to Charge the Battery), or SNU (Solar and Utility can charge the battery together, which will obviously be utility only if you don't have solar yet). If you're using monitoring software like Watchpower or ICC, then you won't see setting numbers like 01 and 16, but there will be equivalents somewhere to achieve the same result (and which ultimately make those same settings changes on your behalf).

Jp poultry Posted November 20, 2021 Share Posted November 20, 2021 I have a synapse5.0+ inverter with a 4.8kw Lithium Ion battery, when the utility goes off and it provides power from the battery, i get error 4 code on the screen (low battery) but the battery is fully charged, even tho it keeps supplying power to my house for 2 hours +from the battery, is this normal or how can i fix this, thank you Quote Link to comment Share on other sites More sharing options...

Ziyanda Posted March 30, 2022 Share Posted March 30, 2022 Hi synse 3.0v+ inverter and two 420 w solar panels and two 12v batteries but now my problem is that it doesn't do anything it shows that the batteries are charging and fully charged only to learn that it never charged at all it just says batteries are low and I struggle to program it to PV only because where I stay there is no electricity please assist Quote Link to comment Share on other sites More sharing options...
Coulomb Posted March 30, 2022 Share Posted March 30, 2022 (edited) 5 hours ago, Ziyanda said: Hi synse 3.0v+ inverter This appears to be an Axpert clone. With 75 V max PV voltage, it's possibly a PWM model (not MPPT). Two 420 W panels in series is possibly too much voltage, especially if it really is a PWM model. Try wiring the panels in parallel instead of in series. Edit: that's assuming that they are currently in series. Does the PV icon come on at all? As you press the up or down buttons, you should come to a page that shows the PV voltage. What does that read?

Often you can tell from the sticker on the side; I have a post with many clues here. Or just post a photo of your sticker here, preferably with a little extra showing so we can see the colour of the screws, the small sticker with the manufacturing date, etc. Quote Link to comment Share on other sites More sharing options...
