    SRNE Split Phase Hybrid Solar lnverter ASF Series 10Kw

    Does SNRE have a remote monitoring app or software? How does it stack up with with APP's/software available for EG4, Growatt, etc. Does is talk okay with Solar Assistant?

    The definitive guide to off grid & hybrid inverters?

    Thanks; The Growatt SPF seem to be very similar to MPP but I believe they make there own grid tie inverters.

    The definitive guide to off grid & hybrid inverters?

    Thanks, that a start. How about SRNE, are they Deye, Voltronics, or someone else?

    The definitive guide to off grid & hybrid inverters?

    Has anyone compiled (and willing to share) a list of all the off grid & hybrid inverters available and how the are related. For example Voltronic, MPP, Growatt, etc. are somehow related using similiar architecture as is Deye, SolArk and EG4 & Luxpower. Would like to better understand the...

    Solarman vs Shineserver comparison? Pros and Cons?

    Taking a look at SRNE inverters which apparently use the Solarman app for remote monitoring. Curious to hear pros & cons from those using the app and how it compares to Growatts Shineserver app. (which has its flaws but after using it for 3+ years must admit it gets the job done). Thanks

    Adding battery backup to existing PV system; inverter recommendation?

    Would like to add whole house battery backup to my existing system. I have 5KW on my house with an SMA grid tie inverter, and 6KW on my barn with a Growatt grid tie inverter. I plan on adding an additional 10KW of PV on my garage with hybrid inverter & battery to supply backup power during...

    Paralleled EG-4 6500EX on a 120V single phase system?

    ksmithaz1 & Tim; Thanks for the explanation. This has been an educational thread. I certainly see the perspective when the power source originates from one generator/winding. Somewhat less initiative if there are two power sources as in the case of paralleled inverters. Speaking of which can...

    Paralleled EG-4 6500EX on a 120V single phase system?

    2 oscilloscopes 2 waveforms, 180 degrees out of sync on the time scale. One phase, 2 waveforms, really?

    Paralleled EG-4 6500EX on a 120V single phase system?

    Totally agree. Here is thought experiment; take 2 oscilloscopes and connect one L1 to N and the other L2 to N. Would each display a sinusoidal wave form? (Yes) And if you were to super impose one wave from on top of the other would you see just one wave form (No) or you would observe two...

    Paralleled EG-4 6500EX on a 120V single phase system?

    Had not heard of this brand but took a look and you are correct. Does EG4 make there own stuff or are they private labeling/repacking the electronics?

    Paralleled EG-4 6500EX on a 120V single phase system?

    Not sure if there is, but certainly not hard to do. Take 2-3K inverters, like my Growatts, configure for 120/240 (out of phase 180 to neutral) and put them in one enclosure and in essence you have a 2 phase inverter. I suspect the 6000XP does the same unless it has a auto transformer, but then...

    Paralleled EG-4 6500EX on a 120V single phase system?

    I know you this stuff better than most so perhaps semantics, but the 120/240 volt system in the US, often referred to as split phase power, involves two 120 V AC lines that are out of phase by 180 degrees with each other relative to the neutral line. This configuration allows for both 120 V and...

    Paralleled EG-4 6500EX on a 120V single phase system?

    Open to suggestions. Can you elaborate why the 6000 XP is superior and how does it provide 120/240 in a single unit. (Autotransformer or 2 internal inverters). Can it run only 120V or must be 120/240.?

    Paralleled EG-4 6500EX on a 120V single phase system?

    Not intuitive why 240 appliances would be more efficient other than than IR loss, I just don't have big power draw loads. My mini splits are all 120 and they are the biggest load. I have split phase panels but have them jumper so both legs are on one phase. That way I don't have to balance...

    Paralleled EG-4 6500EX on a 120V single phase system?

    Growatt 3000's in parallel; they have worked great but buggy MPPT wakeup and monitoring via Solar Assistant.

    Paralleled EG-4 6500EX on a 120V single phase system?

    Considering swapping my existing inverters for a pair of EG-4 6500EX inverters. I don't have an 240VAC loads so wired my system for 120V. My understanding is the EG-4 6500EX is 120/240 with a single inverter (curious to hear how they do that, auto transformer or 2 internal inverters set 180...

    How to reset Daly 100A 16S (48V) BMS

    I have a Daly BMS 16S on three of my battery banks. All connected (via UART) with Solar Assistant. I recently top balanced some of the cells in my bank, before top balancing any of the cells I disconnected battery from main bus bar and removed the voltage sense ribbon cable from BMS. I did not...

    Growatt SPF-3000TL LVM ES; buzz, pop and then goes dead?

    Finally had time to do a more throughout inspection. Found that one of the IGBT's on the main board had blown. These are rated 600V, 80A. Unlikely a voltage problem so suspect either a current issue or simply random component failure. The inverter was not connected to any loads at time of...

    Growatt SPF-3000TL LVM ES; buzz, pop and then goes dead?

    Inverters connected to shared 560AH battery, 2 separate 3KW PV arrays, no grid input, AC output connected to 2 separate circuit breakers which were open at time of failure.

    Growatt SPF-3000TL LVM ES; buzz, pop and then goes dead?

    Recently installed 2 SPF-3000TL-LVM-ES 48. Tested after installation and inverter and MPPT charging all worked fine. (No grid hookup so did not test utility charging) They worked for about a week in MPPT charging mode (inverter side was not turned on as did not have loads attached). After a...

    Growatt SPF 3000TL LVM in parallel with SPF3000 TL LVM-ES?

    Anyone know if Growatt SPF LVM can operate in parallel with SPF LVM-ES? I was hoping they might, as they are very similar models, with the ES version being capable of operating without battery. I have 2 SPF LVM operating in parallel and wanting to add a third and a friend has a ES version they...

    Flashing Firmware Growatt 12kw

    Thanks for sharing this. I had the same problem of getting stuck at Block 2 after erase and had given up. After removing the wifi dongle I was able to flash successfully!

    Bringing LiFePO4 cells back from the dead?

    I was able to recover 48 of the 64 cells. I first charged them slowly at 5A until voltage came up from 0 to 3, then charged them fully at 30A to 3.65V. I did a capacity test then recharged. Capacity of the cells I tested was > 260AH . They are now back in service and working okay. Will be...

    Bringing LiFePO4 cells back from the dead?

    A neighbor ran his 16S LiFePO4 EVE 280 battery bank down to zero while he was gone for an extended period. I am trying to see if it can be brought back to life. I have charged up some of the cells and then tested capacity, and measuring 250-280AH on various cells. Based on a single test it...

    Solar Assistant; trouble communicating with Growatt SPF 3000TL LVM Inverters

    Had not considered a USB isolator before. I assume high speed data and power isolation, like the ones used to eliminate audio interference? Thx

    Solar Assistant; trouble communicating with Growatt SPF 3000TL LVM Inverters

    I have struggled to get stable communication between my Growatt SPF inverters and Solar Assistant running on Orange PI. It works at times but get frequent CRC errors. I have tried different cables, purchased cables with ferrite chokes, re routed cables, wrapped them in foil, etc. Sometime I can...
