Waar het in de beredenering fout gaat is in de situatie waarbij het grid niet meer beschikbaar is. Als het grid wel beschikbaar is dan kan de 2400 Pro aan je huishouden/grid terugleveren. Als het grid niet beschikbaar is dan niet, zoals het hoort conform regels en richtlijnen.
Een P1-meter heeft geen nut als het grid is uitgevallen aangezien je slimme meter dan ook is uitgevallen. Alleen de noodstroomuitgang op je omvormer doet het dan nog, de normale stekker naar het stopcontact mag dan niets meer terugleveren om medewerkers van de netbeheerders te beschermen.
Wacht, ik post mijn volledige vraag even, want die vraag ging juist niet over als de stroom er uit ligt (in mijn initiële vraag naar support ging de volgende vraag daar pas over)
Misschien dat de verwarring is ontstaan omdat ik 'to the grid' gebruikte, daarmee bedoelde ik mijn huis
De vragen die ik stelde
I already have some solar panels (which I cannot convert to go directly into the 2400pro, they are 230volt grid connected via their own inverters), so then I would charge both via the plug (using the p1 meter) as well as via the direct attached solar panels
1. does the 2400pro allow to be charged via direct attached solar panels as well as via the 230v powerplug when there is available capacity (negative usage on the p1 meter)
2. when then batteries are full and there is solar power, does the 2400pro then deliver power back to the grid via the plug for the attached solar panels?
3. In case of long term power outages and relying on the off-grid port, can the 2400pro still be charged when there is solar power via the direct attached (4x 515w) panels?
4. if there is less then 2400watt (or 800 at default config) of solar power, does the unit charge at a lower rate or does it pull more power from the grid?
Het antwoord dat ik kreeg
1.Yes, the SF2400 Pro can be charged via direct-attached solar panels and the 230V power plug simultaneously. The device supports combined charging from PV panels and the grid, with a maximum combined charging power of 2400 W. Using the P1 meter, the system can dynamically adjust power usage based on real-time household load and available capacity.
2.No, the SF2400 Pro does not deliver power back to the grid. Excess solar power, when the batteries are full, will be used to supply off-grid loads connected to the AC off-grid port. The device does not support feeding energy back into the grid.
3.Yes, in case of long-term power outages, the SF2400 Pro can still be charged via direct-attached solar panels. The AC off-grid port can operate normally even when the device is not connected to the grid, and the solar panels can continue to charge the battery.
4.If the solar power is less than the maximum charging capacity (2400 W or 800 W in default configuration), the unit will charge at the available solar power rate. It does not automatically pull more power from the grid to compensate for lower solar input unless configured to do so.
Dus ik verbeterde mijn vraag, dit was mijn antwoord waarbij ik ook aangaf dat ik met grid het huis bedoelde
That was a speedy response, thanks
I don't think I completely understand your answer on number 2 or I am misunderstanding the basic conception of the device
Its my basic understanding that the device charges when there is solar power available and discharges using the same (plug-in) cable to the whole house when there is a requirement for power (to achive 0 on the meter)
But then on answer number 2 the statement is made that the additional power coming from the direct attached solar panels can only go to the offgrid port and does not support flow back to the grid (rest of the house)
is that then true for just the direct attached solar panels or the whole device in general?
and what would then happen if the offgrid port requires more power then the solar panels can deliver?
en het antwoord terug
The Zendure 2400 PRO does not support feeding power back to the grid. Excess power from the direct-attached solar panels or the battery is directed to the off-grid port to supply connected loads. This limitation applies to the entire device, not just the direct-attached solar panels.
If the off-grid port requires more power than the solar panels can deliver, the device will supplement the shortfall with power from the battery. If the battery is depleted and the device is connected to the grid, the grid will provide the additional power required by the off-grid port, up to a maximum of 3200 W.
