You are so clever
1. The grounding of 3000W24V AC output shares the same grounding port as the AC input terminal
2. The grounding screw on the shell of the solar inverter is connected to the ground with a wire
Thank you so much, a very professional guide 👍
Thanks
Hello,
One Question please:
In europe, Mono 220 volts only , Hybrid converter for 48 volts batteries;
What is the "empty consumption" (at night without much load f.i.) of your 6200 or 8200 or 10.200 watt machines?
Thanks
No Load Power Consumption: 50W（6200）, 70W（8200）, 72W（10200）
I'm installing in a van, the A/C out uses only 2 wires, is the 3rd wire (ground) not used?
The third grounding wire of the AC output can be connected to the grounding wire terminal of the AC input
The installation booklet on my new model no. HF2430U60 says "for PV to charge 24v battery banks, you will need a minimum PV VOC of 120VDC". How do I calculate that? I have four, 100W 24volt panels that I will be running in series. Will that be enough?
The HF2430U60 model has a maximum input PV voltage of 100 V. We suggest you to check the label on the inverter case to see if the Max.PV Open Voltage is 100 V or 450 V. If it's 100 V, the startup voltage needs to be more than 30V. If it's 450 V, the first startup voltage needs to be more than 150V, and the subsequent voltages can start up as long as they have 120V.
Then check what the open circuit voltage of your solar panel is. Assuming it is 32V, 32V*4=128V, which is not enough to start for the wide voltage version of the inverter, you need to increase the solar panel.
But for the low-voltage version of the inverter, just 30V is enough to start. You consider 4 solar panels in parallel. Or 2 series 2 parallel.
Can I use the inverter without the AC Out comection? Thank you
Yes
You are so pretty 😍
can I use the inverter without the ac in? I want to be off grid and only have solar in. I hope that makes sense.
Yes, you can use the inverter without the AC in
Note: The initial start-up voltage of the PV of this inverter needs to be greater than 150V Afterwards, the voltage just greater than 120V can the inverter be started.
How can I set 24v battery to set 40% use first at night then keep rest for emergency backup. Thanks. My model is Hvm3.2H- 24v. Do I have to set low cut and high cut?
Yes, you need to set the low-voltage disconnection voltage of the battery to stop supplying power to the load(负荷). For example, if it defaults to 21.2V, you can set it to 24V.
Why Would I need 2 x40 amp Breakers ? Here in the UK our plugs have a 13 amp fuse built in so this would blow first. (ac in ) Also I have wired an extension lead to the AC out which also has a 13 amp Fuse as standard which again would blow, so the 40 amp breakers would not be needed as they would never blow because the 13 amp fuse would always blow first. I agree using a160 amp battery breaker but not sure about the other 2
If the maximum output current provided to the load through bypass is 40A, it cannot exceed this value. Therefore, it is recommended to configure a standard 2P-40A-AC circuit breaker. The 13A fuse is too small and can easily trigger the fuse
where do you connect the ground from the investor to where? you did not show this.
The ground chassi plug would go to an literal earth ground rod.
What do the left and right bars on the front screen mean I cannot find it in the book
Sorry, I didn't understand your question. Can you contact me through email：ysolar@foxmail.com
? It would be best if you could provide photos, thank you!
Can the system work without a solar panel, just with grild alone?
Yes, you can use the Utility or AC generator for charging. It can also be used only as an inverter
What is the idle current of the 24V-H model? Is it still around 70 watts like the 24V ?
Yes
for clarification, in the manual of same item, the recommended wire size is 6AWG.. i am confuse because you are using 2AWG in this presentation. thanks.
Hi friend, battery wire diameter recommended: 30mm ²/ 2AWG;
The recommended PV Wire Diameter is 3.5mm ²/ 12AWG
The recommended AC input/output wire diameter is 6mm ²/ 10AWG
The wire diameter is only for reference In case of long-distance between a photovoltaic array and an all-in-one inverter or between an all-in-one inverter and battery, using thick wire to reduce voltage drop and improve system performance
Where does chassis grounding go?
I‘m so sorry, I didn't understand your question well
I have the POW-LVM3K-24V-H, there's only two spots for AC output no ground, am I supposed to ground it to the inverters chassis? Should I add it to the grounding screw that's there for grounding because you cannot run AC safely without a proper ground.
Hi friend， the grounding of the AC output and the grounding of the AC input share the same terminal (the grounding terminal of the AC input).
@@temank2741 the input side of the AC that would come from the house is not being used this unit is being used off grid
Is the charging mode you have chosen priority for mains power?@@blindvegan
@@temank2741there is NO mains power
You can directly connect the AC output grounding wire to the grounding screw on the housing, and then make the housing grounding@@blindvegan
what are the minimum volts for the inverter to work without batteries? Thanks 😊
Sorry, this inverter needs to be connected to a battery for operation. No support for battery-free loading
Does this means inverter cannot work with only solar panels ??
hi uo to how many solar panel can i put for 24v
Is the purchase the latest version of POW-LVM3K-24V-H? The maximum input of this inverter is: 4000W, 450V, 13A
The total Power must not exceed the PV power when the PV modules are connected in series or parallel-PV power: 4000W
The total voltage must not exceed the PV open circuit voltage when the PV modules are connected in series or parallel-PV open circuit voltage 430V at 25℃ environment temperature.
The total short-circuit current must not exceed the PV short-circuit current when the PV modules are connected in series or parallel-PV short-circuit current：13A
All three conditions need to be met simultaneously
For example, your solar panel is 300W, 28V, 10A
Due to a current of 10A, all solar panels can only be connected in series and cannot be connected in parallel
450/28=16.07, rounded to 18
4000/300W=13.33, rounded to 13
Because all three conditions must be met simultaneously, a maximum of 13 * solar panels （300W, 28V VOC, 10A) can be connected in series.
How to change fuse pow-hvm3.2h-24v
The fuse is usually located at the battery terminal. Use a multimeter to measure and see if the fuse is broken. If it breaks, you can search online for the same or similar fuses based on the current on the fuse to replace it. Alternatively, contact the seller of your order to apply for the original fuse.
Where do I get the 160 breaker
Search for "DC circuit breaker 2p 160a" on shopping websites, such as Amazon or eBay
How would be the connection in mexico with 2 lines 110v ??
Only use one 110V live wire with one neutral wire. It is single-phase 110V AC power. If two 110V live wires with different phases are connected, it means inputting two-phase 220V AC power. This inverter cannot be connected to such a high-voltage AC input.
If there is only two-phase 220V, no single-phase 110V, or no zero line, it cannot be used.
Suggest purchasing 2 sets of PowMr split-phase 5000W solar inverters or a single PowMr 10K split-phase solar inverter
I want to buy the 3200w, 220v
Can I use any type of battery and is there a specific size that I must use?
The voltage of the battery should be consistent with the system voltage of the inverter. For example, a 24V inverter should connect to a 24V battery. And suggested battery capacity greater than 100AH
what will happen if i only use 100 ah
How about generator connection?
The wiring method is the same as connecting to the Utility
Note that if the input frequency and voltage of the AC generator are unstable, it may result in the inability to use AC power normally
I can connect 4 pv 550w in series
What is the open circuit voltage and short circuit current of each solar panel?
Three conditions need to be met simultaneously:
1. The total input power of photovoltaics is less than 4000W,
2. Total PV current
Can I charge it without solar energy?
Yes, you can use the Utility or AC generator for charging
@@temank2741 oh, thank you.
You are welcome！@@obiageliodi8734
