thanks @BGb - the heatpump has been checked and it generally functions normally when the sun is shining and there is no grid power. the heat pump's startup peak current is at most 2000W and my general house load is 1000W max (mostly lights, fridge etc) so at most 3000W. The inverter handles my coffee machine, microwave etc perfectly fine when the load reaches close to 4000W so it should be fine Thanks @Cef - my battery charge seems to reach 3.6KW ~ 70Amps so it think both circuits should be working normally. the inverter is able to handle much larger loads without issue - i think the heatpump is posing a specific inductive load that the inverter just does not like. the interesting part is that if I am generating more than 50W of solar the trip does not occur, tested it a few times this morning between 6 and 7 AM 😕

Hi All, Setup: Inverter GoodWe GW5048D-ES, Firmware: 232315, Software Ver: 410-04025-23, Arm Version: 410-02034-15 18 x 365W Canadian Solar Panels (6.5KW of capacity) 2 x SVOLT 5.09KW Batteries (Inverter communication set to Pylontech US3000C*3) closest config to my setup, SVOLT uses PYLON protocol for comm's over CAN protocol. The SVOLTs are a replacement for my GEL LED Acid system that was installed in 2020, along with the inverter. Issue: I installed an AQUAHEAT 3.5 (https://www.aquaheat.com/_files/ugd/01bcb4_77d00c7b0a67474d883f899c6403464d.pdf) power draw of this is only around 0.87KW and hence is connected to my backup circuit of the inverter. In June my inverter started randomly tripping during the night when there is load shedding and I am on battery backup, the tripping stops when I turn off the heatpump. Given I had been running gel-led acids up to this point, I decided to upgrade my batteries to lithium (finally) - the SVOLT batteries were the most economical and work with the GoodWe (as specified in their technical guides) - this is technically true. Still, GoodWe's battery configuration for 3rd party batteries leaves MUCH to be desired and they don't respond to support emails or pick up the phone anymore (is GoodWe as a brand just dead now?) Anyway, for some reason we just did not have loadshedding during the night for about 2 weeks and in the day I dont have any issues as long as there is 1W of solar coming in the inverter does not trip, ever. Recently, we started having loadshedding from 18:00-20:00 and 20:00-10:00 and since then the GoodWe just trips constantly if the heatpump is trying to heat up the geyser. The total load on the inverter is 2000W (with the heatpump), batteries have 190A @ 48V 10KW of discharge capacity (way more than the inverter can handle) and still is trips. My initial thought was maybe some config or error being thrown by the batteries, so I hooked up a BMS monitoring app with my laptop and monitored the batteries during these trips and nothing, no error is thrown, no communication loss nothing, even removing comms and putting the batteries in self-define results in the same. SO, maybe its the GoodWe, i used @Cef tool and started monitoring the inverter and what I see does not really make sense, I get an error 15, Load on trip was 1230W or 1365 Va, Batteery is at 49.60 V or 92% SOC (22Amps draw). Error Goes 15 (Trip) -> 10 (Restarting) -> 9 (Check) -> 12 (Normal Off Grid) Any thoughts on what could be the issue? Is it just GoodWE?

Is the web portal only available to subscribed users?

I just purchased two 5.09 KWh 48V batteries so far working great. The SVOLT batteries are using a pylontech like BMS communication, so if your inverter supports pylontech then most likely will support the SVOLT batteries.

Hi @Cef thanks for your hard work on this especially for the small community of GoodWe users, my GoodWe started randomly tripping about a month ago, I though it was my Gel Led Acids, so i finally took the plunge and purchased 2 x 5KWH SVOLT batteries (which are working great) but still random trips. Hoping your software can help me out
