I currently have four PV strings connected to a combiner box. I have a fifth string that I want to connect. The specs for the combiner box limits string input to 10a/250vdc per string. The new string is 10.82a/273.6vdc. I know I can't connect the string to the combiner. Can I connect the...

Looking for advice on how to add PV panels to my system. I know others have asked similar questions, but I'm still confused. First some details. Inverter EG4 6000ex (only one MPPT) Max PV input 7500w Max PV Open Voltage 500vdc Max PV Input current 27a PV Panels Sanyo...

I received an email this morning from Signature Solar for their technology upgrade program. The terms are: Customers are eligible to participate in the upgrade program if they have purchased new Growatt 5k’s or EG4 6500ex or 6000ex inverters from Signature Solar. These inverters are eligible...

I currently have three LifePower4 batteries running on my EG4 6000ex, charging and discharging daily. I just purchased a fourth and want to add it to the other three. I know the SOC for all four need to be the same. What I need is a suggestion on how to best accomplish that. The 6000ex has...

I'm running an EG4 6000ex with three EG4 LifePower4 batteries (48v). The batteries are fully charged and I'm getting some solar production. The inverter is running in Solar/Battery/Utility mode so power should come from solar then batteries. But twice today there was a usage spike that...

I'm facing an issue with the EG4 6000ex that I hadn't considered when I bought one last summer. After using this for a while it seems logical to me that, for surge and other requirements, I need a second 6000ex. However, as we all know, they've been discontinued. I'm searching for either a...

I'm trying to understand how several settings for the 6000ex interact with regard to grid charging of the batteries. Here are the options in the configuration: Option 19 Low DC Cut off battery voltage setting (EG4) 20% Option 20 Bypass loads to grid when grid is present (EG4) 30% Option 21 Set...

I've been watching Signature Solar and other vendors who carry the the EG4 6000 and noticed them go from out of stock, to refurbished only and now the refurbished ones seem to be out of stock. Has this particular AIO been discontinued?

I just received this from EG4/Signature Solar support: "I'm glad to see the system is running again, although I would personally not advise using Solar-Assistant as it will burn up the communication card of EG4 inverters. It sends an additional 32V back into the port it's connected to. Also it...

Finally have the 6000EX running but as soon as I connect a load to it (heat gun on low setting connected to 20a outlet connected to a load panel) the inverter faults and shuts down with error or fault 55. If it is an error, the manual lists it as "Over DC offset in AC output". If it is fault...

Really stupid question...how do you power off the inverter? I only have battery and PV connected but whenever I press the power button it only alternates between standby and on. I need to power it off to make some cable modifications.

Wondering if anyone might be able to point me to a source for the hardware I need to mount these panels. They have a lip all around the outside where the clamps fit in to hold them down. Can't seem to find them anywhere. Attaching the installation drawing from the manual in hopes someone...

I have a very used, but operational Sunny Boy 6000US available to anyone who might want to pick it up. It was installed nearly 18 years ago and was removed from service in the last few weeks since we have replaced the entire PV system. It has been reliable that whole time and was working when...

I'm trying to wrap my head around the calculations for what size cable I need running from my battery rack to the my inverter. I have an EG4 6000EX which is rated at 6000 watts. I have three EG4 LifePower4 48 volt batteries. Reading online the calculation for cable size seems to be maximum...

Before I turn this thing on, I'd like to get some verification and comfort that my system will work and be safe. I think I've got things under control but would really like to be sure. I'm still installing pieces but here are the components and the plan: Sanyo PV Panels: HIP-200BA3...

I received my all-in-one and it is heavy (80 lbs.). My plan is to install a 4x8 strand board and some hardi-board over the Sheetrock. I’m going to use heavy duty toggles going through all the layers to support the inverter. Does this seem reasonable? Any suggested alternatives? This is from...

Extreme Nubee... I have 21 older Sanyo HIP-200BA3 solar panels just removed from my roof (long story). I want to use them with an EG4 6000EX (I have a deep well and water pump, limited money and this is just an experiment for now.) I've done some calculations and want to be sure I won't kill...

I've been searching for vendors selling EG4 system and keep getting two-- Signature Solar and Solar Sovereign. I've seen several posts about Signature but when I search can't find anything on Solar Sovereign. Here is a listing from their website...
