Connecting a generator to a Sunsynk 5K
I'm not entirely sure what all that means, but let me give you the information I do have: The generator connects to a welding plug, and there is a big rotary switch to toggle generator input to the inverter. It is connected to the inverter's generator input. On the Battery Setup page, under the Batt charge tab, these are the settings: Both Gen Charge/Gen Signal are ticked, as are Grid Charge/Grid Signal The two fields on the Amps line are set to 6A and 40A, respectively. From what I understand, the first value (6A) is the generator charge current value. Float V = 57.1V Absorption V = 54.0V Equalization V = 50.8V So, trying to match this with what you asked, the generator is connected to the generator input, is limited to 6A (not a specific wattage), and Gen Charge is enabled. I hope that's what you needed.

Connecting a generator to a Sunsynk 5K
Hi everyone, I purchased a Ryobi generator (RG-3500). It's rated at 230V and 10.7A. The sole purpose of this was to act as backup for my Sunsynk 5K system. I don't have solar panels yet, and our area sometimes suffers multi-day outages. The plan was to connect the generator to the inverter, and have it provide power enough for the house and for recharging the battery. All this happened in December, and yesterday was the first time we actually needed this, and the results were underwhelming. The generator delivered a total of 709W, of which nearly 400W went to the house and about 80W to the running of the inverter, leaving only a 220W trickle to charge the battery. I've been discussing this with the installer and Ryobi, and — as expected — they're both saying the other is to blame. The generator is rated at 10.7A, and the installer configured the inverter to draw a maximum of 6A (to compensate for altitude). At 230V, that should deliver 1380W, which is nearly double the delivered 709W. My question then, is what affects this? The generator can pull a 2000W kettle, so I don't think its output is the problem. How should the inverter be configured to draw the configured 6A? Or am I looking at this the wrong way?

Battery BMS not preventing depletion
Hi everyone, Total noob here, and I'm hoping the question isn't completely daft. On Friday, I installed a Sunsynk 5K-SG01LP1, connected to a Greenrich U-P5000 battery. No solar, because my money is not infinite. Solar is definitely the next goal, but I digress. On Sunday, our load shedding ended at 20:30, but the power never came on. So, newly kitted out with protection against load shedding, I went back to the stone age along with the rest of Kempton Park. Here's my question: The battery depleted, and I expected the BMS to cut off the battery supply at around 10%, to protect the battery. The inverter also has a 10% battery cut-out configured, but neither did their job. So, my shiny new battery depleted all the way to 2%. Does that mean the BMS is either faulty or misconfigured? And, if misconfigured, how do I fix that? Second, while the inverter stopped supplying the home at 10%, the inverter still continued drawing about 70W from the battery, depleting it until nearly empty. This setting is then NOT a backup for the BMS.
