Voltage between Earth and neutral on Lux Power SNA5000 WPV inverter load (97V)

There are two aspects to this. A normally open contactor/relay should be installed such that when eskom power dies (input to inverter), the contacts connect (output of inverter) earth and neutral. Now you have a local power plant earth/neutral bond which is a requirement. It MUST be temporary, because when eskom plant comes back online, then you must use their earth neutral bond (Always use the bond closest to the power plant (Power source) that you are using. You are not allowed to have two permanent earth neutral bonds in a system. However, if eskom is available, and your battery is in island mode (Working off battery or solar) then the contactor/relay remains open because eskom is available, and you still have no earth-neutral bond. To fix this, ensure that your inverter is in "Hybrid mode", this keeps the AC Input active/connected even when using solar/battery and hence, the bond before your inverter is still in play. I had an electrician sign off a C.O.C BEFORE this was done! No Bond and NO earth leakage, yet they signed off. Crazy I forced them to come back and solve as per above.

Anyone have an idea on this?

JHB. Thanks

Hello. I have existing Inverter and Battery. I am looking for a supply and install of 4x 500W Panels, to one MPPT input on my inverter. I am battling to get responses from installers. Thanks Tom

I have one Greenrich UP-5000 100aH battery connected to my Lux SNA5000, and the app shows Batt Parallel Num: 1, and Batt Capacity 50Ah. I have selected Battery type/vendor: 2 in the battery menu. If i choose battery type 0, it changes the Battery Capacity to 999Ah. I think something very broken in the software code... but the percentage capacity SOC on the app matches with the battery percentage status on the battery, so Im not going to loose sleep over it.

How did you update firmware on your SNA5000 ?

Hello. Can anyone provide insight into menu 24 on the lux power SNA? FanSpeedSetting. Does fan speed percent set the max speed of the fan? What is Fan Speed New Slope? It can be enabled or disabled Fan1 and Fan2... Any explanation of these?

Green Function Enable: if users enable this, When off grid output power is lower than 60w for 10 minutes, the inverter will turn off the output to save energy source: https://luxpowertek.com/wp-content/uploads/2022/02/ECOHybridSetting.pdf
