| Question: | What is the minimum voltage input from your solar panels |
| Answer: | Your battery is 48V, then your solar panel's voltage need higher than 48V. Or battery can't be charged. |
| Question: | I have 20 260 panels and want to go off grid. If i purchase 2 of your inverters can I link them to supply my house off grid |
| Answer: | YES. |
| Question: | How many can be linked? |
| Answer: | only 1 |
| Question: | one place says "Peak output 7000w, then elsewhere maximum output power: 4200w" then "3500w 48v inverter function" can you clarify? |
| Answer: | 4200w means: when PV charging, solar panel Maximum output 4200W power to inverter charge your battery, inverter only can take 4200w max power from solar panel.
3500w means: when in Inverter mode, Inverter's Rated output power is 3500W; (will provide 3500W power to your Electrical appliances use)
Peak output: 5000VA=The maximum power supplied by the inverter to the consumer is 4000W, which will not exceed this value.
Peak output: 7000VA，Sorry this parameter is a mistake, It has been modified； this parameter is 5000VA；
Peak output: 5000VA is Apparent power, Apparent power is the amount that represents the capacity of AC electrical equipment. Equal to the product of the effective value of the voltage and the effective value of the current. It is multiplied by the power factor to equal the active power. Usually the power factor is 0.8, which means that the actual maximum output power is 5000VA*0.8=4000W； Peak output: 5000VA=The maximum power supplied by the inverter to the consumer is 4000W. |

| Answer: | yes. you can wire Solar panel to this equipment. |
| Question: | How many solar panels of 260 watts can be connected to this inverter. Do they have to be connected thru a combiner . |
| Answer: | nverter's Max power is 3500W, you can wire about 13pcs 260 watts solar panel.
About the combiner, it depens on your system. |
| Question: | Is this a low frequency sine wave? |
| Answer: | it can output 50hz or 60hz |
| Question: | how can i see how charged the batteries are? |
| Answer: | The LCD display will show the charging status |
| Question: | Would I have to pay shipping for any warranty covered parts? |
| Answer: | NO. |
| Question: | The hybrid inverter is installed outside correct? And dose the pv come with the inverter |
| Answer: | Location of install: Please install this inverter in Cool, dry, well-ventilated area: Heat is the worst enemy for electronic equipment.Inverters must be in an area where the fans are not blocked or where they are not exposed directly to the sun. They should be in an area free of any kind of moisture and allow for clearance of at least 8” around the unit to provide adequate ventilation;
PV wire to Inverter's PV terminal (PV+ and PV-). |
| Question: | Can you run 2 units together and get 2 phase 240v? |
| Answer: | NO. This model doesn't have such function. This series inverter has 220V version, |
| Question: | Does the pv solar powered panels come with the inverter? |
| Answer: | NO. Solar panel doesn't contain. need you purchase by yourself |
| Question: | Will this work with agm batteries |
| Answer: | YES. |
| Question: | Can this be used with solar only with no battery? |
| Answer: | NO. it need battery |
| Question: | What is the minimum solar panel voltage input to the unit |
| Answer: | 60VDC |
| Question: | What is the maximum PV volatage input ? |
| Answer: | Maximum PV volatage input:145VDC |
| Question: | What is the warranty? |
| Answer: | it comes with 1 year warranty. |
| Question: | Can this be used solely off grid using solar and batteries or does it need to be wired with the grid |
| Answer: | Both is ok. It has differen working mode for select.
You can only wire solar panel and battery to use it. Or wire your grid to it as another power energy to charge your battery. |
| Question: | Can this inverter work woth deep cycle battries? |
| Answer: | yes. 48V battery |
| Question: | Is idle draw really <25 watts? |
| Answer: | This item's self-consumption is 1A.
It is an integrated product of mppt charge controller and inverter. It integrates PV charging, AC-DC charging, and DC-AC inverter. Compared with a single charge controller or a single inverter, its own loss will be larger.
About no-load self-consumption: For the same power, the lower the input voltage level, the greater the current flowing on the input side, and the more components required inside the product, so the greater the loss. The size of the no-load loss has an important relationship with the circuit design, device options, and the number of components. Because the device wants to work, it must provide them with voltage, even in standby, it must also provide standby energy. |
| Question: | Can this inverter work with 120 voc from solar panels or what is the max voc this inverter can handle? |
| Answer: | es. The max voc this inverter can handle from solar panel is 145Vdc. |
| Question: | If max charge current is 30A at how many volts? |
| Answer: | It doesn't have such fix voltage parameter. |
| Question: | Can i manually set the charging perameters for lithium batteries? |
| Answer: | YES. If you wanna set your own parrameter you can choose USE, all battery parameters can be set.
And also it has pre-set parameter for Lithium iron phosphate battery LF14/LF15/LF16,14strings ,corresponding to 15 strings and 16 strings of lithium iron phosphate battery. |
| Question: | Is this a grid tie inverter? Says hybrid. |
| Answer: | is off grid inverter.
Hybrid means it have 48V inverter function and also with MPPT charge controller function. It is all-in-one solar charge inverter. It support use AC Mains power/Solar power/ generator power to charge your battery.
And Its Output is 110V AC power. |
