Thank you very much , that’s what I thought I should do . I’ll get a separate ground bar screw It to box and then connect my grounds to it . No the house panel doesn’t have the neutral and ground bonded , it is connected to a ufer but that’s all .

Hi . I’ve got a solar system in the process of being sign off by local state inspector . And he s giving me trouble claiming the compatibility between my inverter ; Outback radian 4048a and flex max charge controller with the new ethos 10.2 kw lithium ion battery ul certified . Outback says...

Thanks for your answer . This is what I made sure of before . I asked both manufacturers , Outback and big battery about their compatibility of their specific combination together : And they both said it is . What more could I have done ? And can the inspector be above any listing...

Really good advice . Thank you

Hi . So I’ve got a utility shed with inverter where the ground is connected to the neutral bar since it is bonded and first point of entry . I then get ac from inverter to a panel in the shed which distributes from there directly to the house . I have to put a disconnect box on the exterior...

Thank you for your help . Have a great day

Here is the disconnect

There is a ul listing for each battery and brand Inverter that says they ll work together ?

Please see pictures attached . It’s 240v coming from shed where the bond between neutral and ground is already made . And I’m wondering where to place my ground in the disconnect ( pictures attached ) since I don’t think I should connect it to the neutral bar or maybe I should ?

Given the rarity of this occurring . They then limitate the choice for consumer to 1 or 2 combinations … I’ve talked with solar installers and they all said that as soon as it’s ul certified and inverter and cc compatible with lithium ion batteries , which is the case . The comms of the system...

I apologize I do not have a diagram . What would need to know more ?

If that’s the case . I m just good to throw away a 4K $ battery and same price inverter ….. great . I can’t believe tech support of any manufacturers don’t know that then …

Manufacturer said it’s compatible .

How would you formulate your question then ? Other than « is this battery compatible per state inspector concern with this inverter and cc ? «

Do you have a screen of the nec 2020 where this new regulation is written down ?

If it’s a power trip it’s pretty pathetic … but anyway . I did show them the 9540 and 9540 a of all components in my system . He s the one actually that did tell me before « just make sure the battery is ul certified and that your inverter and cc are compatible with lithium ion batteries «...

Here it is

Thank you

Shame one might have to go through such ways … especially on a system that works perfectly so far .

They do see the attached docs that I sent
