Very well explained. Voltage Drop is often overlooked in all aspects of electrical design resulting in power being lost to heating (and possibly damaging) the wire.

6:39 here to reduce wiring cost we also buy another solar panel which is way expensive than the now (76$) to then (90$) wire cost :D so i dont see increasing solar panel voltage leading to wire cost savings 😅

I know W=VA now. Thank you. Can we use solar panel of different brand names in the same system please? Or do we have to use same brand names of controllers, panels, inverters and batteries, please?
@cleversolarpower3 ай бұрын
VA*0.8=W for example, the victron phoenix inverter with 1600VA has a power rating of 1600*0.8=1280W. You can use different brands. But for solar panels i would use the same brand and model, because they all differ a little bit ,which will lead to losses. Check my video about 'mismatched solar panels'.

@matthewwakeham22063 ай бұрын
Victron require the use of fine stranded flexible wire with their solar charge controllers as solid wire doesn't give a good connection in the terminals which leads to heat and fire.

What is the logic behind the 1.56 safety factor add to the current? How will the panels make half again as much current? Isc is shorted out so that is the maximum current it can put out. I see 1.56 applied to the input current of a charge controller if it isn't continuous use. How does this apply to current in a wire
@cleversolarpower6 ай бұрын
It accounts for higher temperatures in the wire in an outdoor setting. Higher temps means reduced current carrying capacity of a conductor.

Just came to mind I have 10 gauge, but at the connections, the wires are very, very small/thin gage , so does that reduce the 10 gauge down to these small wires? Causing big energy lost? Thats how the wires came from manufacturer.
@cleversolarpower5 ай бұрын
Do you mean the terminals are too small to fit your wires? Then I assume your panels are in parallel. Check the maximum input current of the charge controller as well. You can add another charge controller to spread the current out.

When you string solar panels together in a series, the voltage adds up. 1000 ÷ 20 = 50. 50 is the maximum number of solar panels ok.

Solar panels have a limit, of how much voltage they can handle (once connected in series . It may be around 1000V for many models. Additionally, solar inverters have voltage limit too, it can be something like: 160V starting voltage, 600V optimum working voltage, 1000V maximum working voltage, 1250V open circuit voltage. In this case- inverter will turn on once it receives 160V, and be most efficient if it works at around 600V. To get that, you divide 600V by panel working voltage, say 43V, and get 600V/43V=~14 panels in series is optimal, and 1000V/43V is 25 panels in series is max the inverter and panels can handle.

(600V*0.8)/43V=11 panels in series.

There's a need to be careful when designing series PV Module circuits. The voltage increases in cold temperatures, and that needs to be accounted for, so we don't exceed the maximum voltage of the MPPTs, conductors, and terminations. I recently saw a video where the guy used WAGO connectors on his PV wiring. They're only rated for 300 Volts. But series PV strings go up to 600 Volts.
@cleversolarpower5 ай бұрын
Indeed, this relates to the max input voltage of the MPPT. I made another video about sizing a charge controller, where I discuss this in detail.

I don't recommend connecting solar panels in series at all. You need AMPS to charge batteries, and you need a charge controller that will handle the AMPS being sent to it. I have four LiFePO4 batteries in parallel (400AH). I have Qty 4 Solar Panels (100 watts each). 100 Watt Panel = 5.25 Amps +, Qty 4 Panels = 21 Amps, sometimes a little more, possibly 22 or 23 Amps on a good day. Charging the batteries at 22 Amps or more is pretty good. We need Amps, not Volts. A 100 Watt Solar Panel only needs a 16 to 14 AWG Wire to carry 5.25 Amps plus, however, once you bring it all together, you'll need a 12 to 10 AWG Cable to carry 22+ AMPS to the Victron 100/30 Smart Controller. I use 32ft. of 10 AWG Wire (rated to 30 Amps) to be safe. I power a small college refrigerator and two freezers using a 3000/6000 Watt Inverter, pure sinewave output signal. From the battery, I'm also using a Victron 500 Smart Shunt. It's all monitored on my cell phone, through Bluetooth. I works great.

This is not true. The mppt will convert the voltage into current because power=volts x current. Power in equals power out - efficiency loss. I recommend watching my video about pwm vs mppt where I discuss how current transformation works.

As a quick side note, you can look up "AWG table for power transmission" as a quick reference without having to worry too much about temperature or distance. The maximum amps for "power transmission" purposes in the official AWG table is a very conservative number that will result in minimal voltage drop at full load. So, for example, by this table 10 AWG is 15A. For people used to dealing with amps and cables, that might seem like a low number, but that's the actual specification "for power transmission". (For copper wire). Most Solar panel cabling is 10 AWG or 12 AWG. Certainly on larger panels. Little panels have thinner wires but also produce fewer amps. It isn't usually a problem unless you are paralleling a lot of strings. Using a combiner box with proper per-string fusing becomes very important in that regard. Plus you can also easily use a lower-gauge solar cabling for your higher-amperage back-haul from the combiner box to the charge controller / inverter. -Matt
@salsepulveda4945 ай бұрын
The table you're using is incorrect. In fact, 8 Awg is 40 Amps, 10 Awg carries up to 30-35 Amps, 12 Awg is 20-25 Amps, 14 Awg is 15 Amps, and 16 Awg is 13 Amps. Of course, 10 Awg will also carry 15 Amps. Just Google Amps vs. Awg size.

@@salsepulveda494 There's a big difference between what a cable can carry and what a cable should carry. For continuous power transmission you want low losses and low temperatures, and you learn very quickly not to under-size cables. Otherwise your efficiencies go straight down the tubes. These aren't toaster ovens that see minuscule duty cycles. These types of systems run their max power for hours each day without a break. I'm using the correct table. -Matt
