Yes - that's the one option - to have the grid feed inverter feed PV energy to the second inverter. Yip I think you're right - if I am running a cable and can use cheaper cable like suffix, less loss - array voltage around 350V

I have a PV array on one building connected to a grid tie inverter. I have added a Sunsynk 5 kW with battery in another building to provide power during grid outages. Its is not possible to have the Sunsynk in the same building where the PV array is, there is no space to mount it with the battery. So the question is how to get PV power to the Sunsynk? its either a long run of DC cable (25m) or some setup where the grid tie inverter feeds the generator input of the Sunsynk. Solar DC cable expensive. Is there an issue with using normal AC cable of the right gauge if it's in conduit? Any ideas welcome. Rob

I notice that Segen Solar have put out a notice saying that the newer Pylontech batteries do not currently work with the Kodak inverters (Axpert) and need to be treated as dumb batteries. Kodak User settings.pdf

Thanks for info.

Hi All, I have an Axpert King 5 kW with a very tired set of agm batteries. I want to get a lithium battery that will communicate with the inverter. The manual and settings refer to pylontech. Does anybody have experience with what batteries are compatible (i.e. communicate properly) with the King. Main firmware version: 71.90 My options are Hubble AM2, Greenrich UP5000, Kodak BL5, Pylontech US3000, Pylontech UP5000 Any advice would be most welcome. Thanks - Rob

I was told by a Sunsynk technical advisor to permanently bond the inverter output to earth. He maintained that this was safer than a bonding relay as the relay could fail. A number of electricians I know who install inverters follow this practice.

I really believe this is the next step with domestic power management. Weather based power generation like wind and sun on a utility scale already has very stable and accurate predictor models. I'll follow with interest.

A client has asked me about using a lithium battery with that inverter. Some smaller inverters have issues with lithium batteries because they can't set their low cutoff voltage properly and when discharging the battery is at risk of BMS cutting off - needing a reboot. What's your experience?

It seems one needs to be ultra careful about connecting any inverter with grid feed potential with the HXE310-P meter. If it trips there seems to be no way of resetting it short of getting City Power to reset. How did you get the problem solved?

HI - Any recommendations on a supplier that I can get a few odds and ends for solar installation. Walk in. No time for mail order. Thanks.

@AndrewRyan, divergent question: The Luxpower SNA does also seem to feed into the grid side. I cant find any detailed information about the difference between how it works and the LXP. There is a big difference in price. I am guessing the SNA does grid blending at a DC level like the Apert King where the LXP does proper blending at an AC level. What are the significant differences? Rob

Just a random note. Growatt tech support is hopeless. They may make some good products but to get anyone to understand anything that you cant get out of the manual is scary.

@DJI I would. Either the supplier must offer a fix or take it back. Which model do you have? If you are going to use an Axpert type inverter go for Kodak as they have proper backup and 3 year warranty.
