# 330 watt solar panel how many amps

When a 12V solar panel is rated at 100W, that is an instantaneous rating, if all of the test conditions are met, when you measure the output, the voltage will be about 18 volts and the current will be 5.55 amps. This means that on that scenario the solar panel delivered 60 Watts of power to charge the battery. Use our electrical conversion calculators to calculate electrical properties given other known values. No. 8 panels in series and in parallel to the other 8 panels. and is this an acceptable configuration/, hi im very new to solar, have been told to install 20 panels 330w, on both east and west and 10 due north, will that work with fronius sc primo 5kw inverter? Connecting Solar Panels to Wires going to Charge Controller; Qty: 40 – 10 AWG Black Wire. Hi Ian, without more site-specific information I can’t really say however roughly it sounds about right but it won’t leave any power to charge your batteries on overcast days. I have an Outback Lino 5KW inverter MMPT charger . To calculate amps, remember the equation amps x volts = watts. Please email us or give us a call if you have any questions. Hi Ali, hello from Australia! Converting watts to amps for a single-phase AC circuit with power factor uses a slightly different formula. A 300 watt solar panel on a 12 volt system should have how many amps in it? 120 Watts / 18v = 6.6 Amps Please note that Solar Panels are not 12v, I repeat Solar Panels are not 12v. Hi David, I don’t know the information about that solar controller, you would need to get it confirmed by the manufacturer that you are allowed to input more than 10A of solar into the charger. UNBOUND SolarEdge Gridtie System for 24 Astronergy 72 Cell Modules $ 12,406.00. ... need to know as to how to calculate the number of 330 w or 150 w solar panels. Small solar panels traditionally come in three common sizes: 50 watt, 100 watt and 160 watt. Complete 350 watt solar system. 70440 NSW Lic. However, if you are going to use 300w panels you will require 33 (10,000/300) panels. Hi James you are spot on with your calculations, the best way to wire your 12 x 325W solar panels with a Victron MPPT 150/85 controller is 4 strings of 3 in series, which would give you a 112v input at 34.4A, well within the charge controllers specifications. Each string would have an OCV of 29.92 say 300 volts giving me 2 x 300 x 16.62 amps. will 5 panels produce enough voltage for the inverter to work? I am a little worried that the Operating voltage of each string might be too low for inverter to operate efficiently. Convert the amps to watts with our electrical conversion calculator, plus learn the formulas for DC, single-phase AC, and three-phase AC circuits. Yet, you can also find panels of 150, 160 or 175 watts. Hi, I want the clear formula for getting NUMBER OF PANELS required for 10 kW inverter. But for argument sake let's say you get a 4 Sun Hour Day. Gold Coast (AUS)Brisbane NorthBrisbane SouthOther Does anybody have measured notes for belowed question. I wish to attach a solar system that could still supply enough Amps at low luminescence to charge the battery at the 10A maximum while not harming the unit at full luminescence, with my greatest concern being overvolting from shading. Calculate the electric charge in a circuit using the capacitance and voltage. Panasonic 330 watt Module 96 Cell HIT - Black Solar Panel Installation PDF Download Our Solar Panel Guide We'll teach you the key factors that influence solar panel … It is not possible to convert watts directly to amps without also knowing voltage or resistance. I’m not completely sure I have your question right, are you looking for a solar inverter with a maximum voltage of 60V? This information can be found on the solar panel manufacturers data sheet, please see example here. Personally I’d recommend an additional string of 3 panels. For three-phase AC circuits where the line to neutral voltage is known, the formula to convert watts to amps … The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V):. To calculate the energy it can supply the battery with, divide the Watts by the Voltage of the Solar Panel. I (A) = P (W) / V (V). Thanks. I found out after they left they have configured each string in a series-parallel setup. That I would have 92 VOC but 76V Vmp. Hi Chad, we would need to know the voltage characteristics of the solar panels in question to confirm this. So, if you have a solar panel that with a 10 Watts power rating and it is exposed to sunlight for at least 6 hours. You would be operating the solar panels outside of the manufacturers’ specifications, therefore all liability would fall on you. I have 4 100 watt solar panels (HQST) brand,also 30 amp HQST MPPT charge controller.The panels are wired in series (83.5V , 5.6 A. So if 50% discharged, it would take 15 hours (about 3 days) of good sun to recharge your system. Depending on the configuration of the panels (series or parallel) the calculation is different. Email (required) EmailCall during business hoursCall outside business hoursOther - Please specify in message above, When you talk to us about solar power systems you can be confident that you are dealing with a team who are extremely experienced in the area of solar power…, Warehouse/Office Location 50O VDC OCV max.PV array. Hi Chaitanya, the number of panels you need will depend primarily on the wattage output of the panels you are looking to purchase. Working out the maximum voltage that your solar power system will reach is not a straight forward thing as it requires information from the solar panel data sheet and some site specific information be entered into our solar panel maximum voltage calculator to calculate the maximum voltage the system will see. 1. if the batteries are FLAT ie under say 12,5 volts then on a good sunny day at the peak of the day you would get say 8.0 amps (100/12.5) based on a 100w panel. Amps to Kilowatts (kW) Electrical Conversion Calculator, Capacitance to Charge Electrical Conversion Calculator. 229221C ACN 131 836 621, Detailed Calc: solar savings with a specific size system, Basic Calc: Sizing Solar to Cover Daytime Consumption, Detailed Calc: Sizing solar to cover day time power consumption, How do I make the most of the feed in tariff, SolarEdge Solar Inverters & Power Optimisers, Tesla Powerwall Home Battery – Existing Solar Power Systems, Effekta solar inverter data sheet manual and common error codes.
