Well, I tried new cables, and a completely different computer (with usb 2) - and latest drivers. The COM port is seen when connected to inverter, but I still cannot update it. I have not located a laptop (or older desktop) with a db9 serial port on it... I've asked around. Signature Solar...

Thank you so much, I appreciate your quick answers. I have read all of your posts, and will continue to try alternative cables, and see if I can locate an older computer with an actual serial port If I make any progress I'll post here accordingly.

Hi Thanks! Yes, I have been patiently working with Signature Solar for over 3 weeks now as I have in the past (and when I do get them on the phone, they have been very helpful). However, I'm a bit frustrated now, and still looking to try to repair it going down other avenues. This seems like a...

Did you ever find a solution? I am now having the same issue on my EG4 6500 from Signature Solar

Yes, mine is fully grid connected. See the attached schematic for details - still not sure about the panic button, will probably add that too. Also, i am not sure if the fusable disconnect on the outside is required, as my meter can/first panel has a service disconnect 200amp breaker, but it...

Hi. see my full comment below yours, but question: If you hit the panic button shorting the pins (B,B), it will kill the inverter's AC output, effectively de-energizing the main ac panel. Is there any danger to the Sol-Ark 15k if this were to happen? Also, please correct me if I am wrong with...

Yeah, here in Florida, I'm told it is required to have all disconnects on the outside for code (at least here in palm beach county). And recommended to have a rapid shutdown if possible (although not a requirement). So, looking at my diagram (attached), the inverter, batteries and subpanel are...

Ya, this bypass switch needs to be whole house cutover / UL rated, etc... it was expensive (like $800) but works perfectly, and passes code.

is that rated at 200 amps? but yes, that's the idea

Ok, panic button to do a "rapid shutdown"... very cool. Some say it may hurt the inverter, cannot find any definitive talk about this. I do have a question - take this scenario (see the attached chart) So, outside the house, there is the "PV DISCONNECT", which would stop all dc power flowing...

My experience is that the Sol-Ark will not pass through with power off. So, I installed it this way... A simple three pole bypass switch - "grid / off / solar" - to my main panel. I dunno, I like the "manual" cutover/bypass myself. Less stuff to break. After this was installed, I was told...

I put together a quick visio (quick and dirty) - but this is one sol-ark.... I would think you can stack them across as necessary, I think this is correct... standard wiring, with bypass: any thoughts?

i would think so too. ya midday and full sun. i don’t understand why it might be acting this way or why it seems like only one inverter is being drawn on. it’s a mystery. open for suggestions.

ok, so what would happen if only one of the two inverters had pv connected…. 2kw and 4kw on pv1 /pv2 respectively and if inverter 2 had no solar turned on. I would expect the draw to properly come from battery…. would that cause draw on box 1 only? the settings are solar first, then...

I have 6 x eg4 batteries all connected in the rack in parallel …. 30 kwh approx. 00 2/0 (2 ott) cables between inverters and bus bar and 00 4/0 (4 ott) between bus bar and battery rack bus bars. It should handle that much power and then some.

All good questions. I don't have the answer to either of those although I suspect they are "overloading" a rs232 port on an existing hardware solution and using it as rs465, so not actually mixing protocols. As an engineer, I would have designed this a little differently, but that is a...

Hi All, I have a pair of VBHN330SA17E panels with the attached Enphase IQ7X Micro-inverters attached. These are NEW/Never used. I purchased them about a year ago for a project and abandoned that project. My loss is your gain. DC Max Power - 330W Peak Output Power...

After 1.5 years, The Outback/Kilovolt solution is still working flawlessly. Note, I have also purchased and built a Growatt solution with a bunch of EG4 batteries from Signature Solar for a different purpose and those rack mount batteries have also working flawlessly for the last year...

I am having the same issue with my pair of 6500's in split phase but mine is above ground - a 2 hp well pump. It simply will not start. When it tries, all the voltage drops on both legs enough to dim the lights and cause my ups to beep (like a power hit on grid).... then bounces back to...

Yeah, that's the second thing I'd do.... it happened to me too... first - check the cable carefully - both ends - to make sure the rj45 connector is crimped on cleanly and completely. Then, make sure it is seated properly in the rj45 jacks on both ends. I have noticed that the original...

it is because the connection is between RS232 and RS465 - if you look at the pin explanations, it matches - if you use a straight through ethernet cable, they are not going to meet as needed.

The only thing I can think of is there may be a setting inside the GW to allow communications out the USB port.... I don't have that model, so not sure. You can also shoot the folks at SA an email, they are very good at responding.

Question about your well pump, what is the "starting" power requirement?

I have had good luck with ES5000 as well as the 6500's. Both were connected to the raspi through the USB connection. I suggest that you connect a "STANDARD" usb cable, (not modified to the rs485 port) directly to the usb port on the Growatt.

Hey there SolarQueen (From AltEstore where I bought the KiloVault). Everything is working perfectly fine now - the SOC is calibrated and the system is working optimally. I was wondering if the firmware would ever be updated so I can connect to it via a rest api and collect data for my home...

Hey Will, I absolutely love your channel - it has helped me a tremendous amount over this past year. Your way of explaining everything is awesome. I have a completely off-grid system, it currently has: one Kilovault 7.5KW battery, one outback front end (Specifically, the Outback...
