  • Voltronic/MPP idle consumption - turn inverter off at night automatically?

    I have Voltronic Axpert Max 8kw. I don't need the inverter to be on at night. Now I physically turn the on/off button every morning and every night. Is there a way to do this automatically?
  • Voltronic aio inverter turn on and off in only solar mode (Bypass mode?)

    I have Voltronic Axpert Max 8kw aio inverter. Is it normal that it turn on and off when it's in only solar mode? Or is it called bypass mode? The inverter model uses a latching push button for on/off, and it's when in off position it turn on and off in the morning when the sun is raising and...
  • DIY Solar panel mounting brackets for pitched tile roof

    I was going to order a lot of solar panel mounting brackets for pitched tile roof and when I discovered the price I was thinking maybe it's cheaper to build the brackets from angle brackets in the hardware store? Has anyone done this before?
  • Do I need isolator/solar disconnect when I have breakers?

    Do I need isolator/solar disconnect when I have breakers? Can I just turn off the breakers when doing maintenance on the solar panels? Like on this picture?
  • Voltronic, MPP, EG4 aio inverter modes and configuration

    I have Voltronic Axpert Max 8kw aio inverter (version 1). I'm reading the manual and try to understand the modes and configure the inverter. I believe it's similar to mpp and eg4 inverters. What is happening in the following modes: 1) line mode 2) standby mode 3) fault mode 4) battery mode...
  • Solar panel with strange ampere/watt behaviour

    I have an old panel, don't know how many watts. The 2 first minute is normal but then the solar panels output is strange. The ampere/watt behaviour is jumping constantly after the 2 first minutes. If I reconnect the panel it takes just seconds before the strange behaviour appear. If I wait...
  • Using wood/plank/barge as mounting rails for solar panels on the roof.

    Is there any issues with using wood/plank/barge as mounting rails for solar panels on the roof? It's much cheaper but it's almost no one using it. Is there a reason not to use it? I found just one guy on YouTube using it:
  • Zero-export inverter, not backfeed to the grid

    Is there a inverter that supplements/ties with the grid, but does not ever backfeed the grid? When I search it seems this is called zero-export inverter, is that right? Or is it called limiter? I see it's something called zero export to ct, but I don't know what ct means? I just wanna use solar...
  • Solar configuration

    Let's assume I have 40 panels 250w Isc 8.9a Voc 37.8 What is the best panel configuration for the MPP MAX 11KW? It has max 18a pv input current... sunshine_eggo wrote on diysolarforum: Current limit is more flexible. Going a little bit over the current limit is typically fine as the unit just...
  • JK BMS - weak bluetooth signal

    I have a JK-B2A20S20P BMS in my battery room but I want to extend the Bluetooth signal. Is there a way to do this?
  • Choosing Voltronic Axpert Max offgrid inverter

    I'm in the process of choosing an Axpert Max offgrid inverter at https://www.solarpower24.it/category-product/inverter-en/off-grid-inverters/primo-max-en/?lang=en What is best of SP24 and Voltronic? What is best of Max1 and Max2? My impression from threads is Max1 is more tried and solid, is...
  • Bus bars Lifepo4- not enough space

    If you look at the picture there is not enough space for a nut on the top of the Bus bars on this Lifepo4 battery. How can I solve this? (3p4s configuration)
  • Connecting solar panels and battery bank to aio inverter.

    1) I have connected a16a circuit breaker into the pv input on the aio inverter. The breaker is in off position. If I connect 6 230w solar panels in series before turning on the breaker, will it spark or do I have to precharge with a resistor? 2) I've connected positive and negative from the...
  • Ferrule on circuit breaker?

    I have some DC circuit breakers and when connecting an apropiate wire it feels loose even when tightening the screw. Is the solution to use ferrules on the wire?
  • JK BMS to Voltronic Axpert Max 8kw communication possible?

    1) Is JK BMS (1.gen B2a20s20p) to Voltronic Axpert Max 8kw (version 1) communication possible? 2) How? 3) What would the benefits be?
  • Low voltage from solar panels to inverter

    I have 6 230w solar panels in series and I'm installing my new aio Voltronic Axpert Max 8kw inverter. When I measure directly from the 6 solar panels in series on a cloudy day my multimeter shows 200v. But when I turn on the breaker between solar panels and Inverter it suddenly shows just 85v...
  • Grounding information on Voltronic Axpert Max 8kw (version 1)

    Anybody have grounding information on Voltronic Axpert Max 8kw (version 1)? It's not listed here: https://diysolarforum.com/resources/grounding-details-for-specific-make-model-of-inverters.156/reviews
  • Solar configuration Voltronic Axpert Max 8kw

    Is it safe to combine these panels in parallel, x6 in each string, and connect to one of the two pv inputs on Voltronic Axpert Max 8kw? The Voltronic inverter has max 450v and 18A per pv input. 6x 260w panels Voc: 38.1V (38.1x6=228.6) Isc: 8.98A Vmp: 31.1V Imp: 8.37A 6x 230w panels Voc...
  • Used / second hand Solar panels in Europe

    Where can I buy used / second hand solar panels in Europe? I live in Norway and shipping/delivery costs from USA is too much I think. I've searching on ebay but hasn't seen much. Any name on solar installers in Denmark, Sweeden, Germany? I'll ask if they have any left over panels from an...
