Circuit Wizard 150 Portable
Hi! I'm building a portable solar generator for RV dry camping with my family, and need some help sizing the charge controller, and validating my findings so far. Basically, my needs are to be able to run a couple small fans, charge devices, and intermittently plug in small appliances as needed for long weekends and the occasional weeklong trip.
Hello, jtysonwilliams. Nice work on the wiring diagram. As it happens, I'm doing similar things with a portable emergency/camping power box also built around a 100AHr LiFePO4 battery (Relion RB100). I'll preface this with the note that I haven't yet installed and tested my SmartSolar 100/30, but I can offer some notes.
I opted for (2) panels for 200W capacity anyway, so voltage won't be an issue for me in series with the Victron controller. Other panels have different Vmp: for example the HQST 100W operates at 20.6 Vmp. The Victron panels operate at 19V. Even Renogy's non-Eclipse 100W model is at 18.6 Vmp. So you have single-panel options that would still allow you to charge at any time with just one panel. I connected my two panels with a piano hinge and turned them into a 21" x 41" x 3" (folded) portable unit.
[It gets a bit more complex if both are ever charging simultaneously, because you could run into issues with voltage detection in the smart charging circuits (each could see the voltage of the other charger as reason to stop bulk charge), but absent that, both would contribute their amperage to charge the battery.
Couple of wiring comments: Make sure you have a switch on the inverter so you don't suffer from parasitic load when it's not in use. Re: wire gauge, consider whether you might ever decide to upgrade to a higher-wattage inverter. A 600W unit is rated for 80A draw in a surge, plus you've got the 15A draw on the cigarette socket side. The Blue Sea circuit wizard is a useful tool: . Easier to overbuild your wiring now than replace it later, but it's obviously a balance, and if you're building a box like mine, distance is fairly short.
To speak to seb71's comment about trying to stick to DC loads, I'll just observe that as part of my tinkering I picked up a 12V buck-boost converter, popped powerpole connectors on it, got a powerpole distro block and made some 2.1x5.5 and 2.5x5.5 DC cables, and I can run my entire home network off this power box. That includes cable modem, router, switch, Synology NAS box, VoIP box, mini-PC and portable screen, backup hard drive, etc. I have 12V USB chargers built into the box, and even 60W USB-C and MagSafe cigarette-lighter chargers. I'm now considering the value of a 12V chest fridge that would eliminate the ice management and sometimes questionable food safety on a longer camping trip, and also serve as a backup fridge. There's a whole 12V ecosystem out there. I still picked up an inverter for various uses.
TheCAPWIZ Capacitor Wizard CAP1B by Midwest Devices is an extremely fast and reliable device designed to measure ESR (Equivalent Series Resistance) on capacitors of 1uf and larger "IN CIRCUIT" eliminating the need to remove the capacitor for ac curate tests. The Capacitor Wizard CAP-1B finds BAD caps IN CIRCUIT or out of the circuit!!
Helps protect against accidentally damaging the Capacitor Wizard by attempting to test charged capacitors. Make a habit of following good service practices and discharge all capacitors before attempting a test - even if you install the CapSVR. Always remove power from the circuit under test.
We will also be using Circuit Wizard software throughout the course. A number of component circuits that can be opened in Circuit Wizard can be found on the Electronics in Schools website.You will need all the Microsoft word skills you can get. Use the following website to learn more about how to do different things in Word. Open Office is an alternative, but if you use Open Office please submit your work as RTF documents. Students are welcome to submit their work as PDF files. You will also need to submit any Circuit Wizard files associated with your assignments.
Schematic Diagrams and Component SymbolsYou will need to interpret symbols in order to construct electronics projects, read more about them here. Additionally schematic (circuit) diagrams are very important.

In a stationary scenario (no help from alternator or shore charging), it's almost impossible to sustainably run an A/C for extended period. A massive battery bank will buy you more time, but solar alone can't fully recover the energy and top up the battery bank. In that case, a generator may be needed. For vans, a portable generator connected to the shore power inlet should suffice (in other words, the generator acts as the shore power source):
The ampacity is the maximum current that a wire can carry continuously without exceeding its temperature rating. For example: if a wire has an ampacity of 45A (AWG 12) and there is a continuous current flow of more than 45A for an extended period of time, the wire could overheat and the insulation get damaged, creating a fire hazard. In the case of a short circuit where current is very high (still a real-world scenario), it could look a bit like this:
The Energizer PPS160N 153.6Wh(48000mAh) Portable PowerStation Power Bank is a lightweight, fast charging solution, providing rapid and reliable power to a wide range of smartphones and devices.

The Demolition Safety Light is a safe electronic device specifically designed for checking the continuity of firing circuits or electrically initiated pyrotechnic devices. The "DSL" will ensure that your electrical wires have a complete circuit, so that your matches and squibs also have a complete circuit.
It's easy to use - just touch the leg wires to the copper disks and the red light will come on, indicating a complete circuit. Use it to check all your firing leads to ensure that there are no breaks in the wires.
(5) Neutral Conductor.(a) A neutral conductor that carries only the unbalanced current from other conductors of the same circuit shall not be required to be counted when applying the provisions of 310.15(B)(3)(a).(b) In a 3-wire circuit consisting of two phase conductors and the neutral conductor of a 4-wire, 3-phase, wye-connected system, a common conductor carries approximately the same current as the line-to-neutral load currents of the other conductors and shall be counted when applying the provisions of 310.15(B)(3)(a).(c) On a 4-wire, 3-phase wye circuit where the major portion of the load consists of nonlinear loads, harmonic currents are present in the neutral conductor; the neutral conductor shall therefore be considered a current-carrying conductor.
Some multimeters have a continuity check, resulting in a loud beep if two things are electrically connected. This is helpful if, for instance, you are building a circuit and connecting wires or soldering; the beep indicates everything is connected and nothing has come loose. You can also use it to make sure two things are not connected, to help prevent short circuits.
Some multimeters also have a diode check function. A diode is like a one-way valve that only lets electricity flow in one direction. The exact function of the diode check can vary from multimeter to multimeter. If you're working with a diode and can't tell which way it goes in the circuit, or if you're not sure the diode is working properly, the check feature can be quite handy. If your multimeter has a diode check function, read the manual to find out exactly how it works.
Alternating current (abbreviated AC) is current that changes direction, usually many times in one second. The wall outlets in your house provide alternating current that switches directions 60 times per second (in the U.S., but 50 times per second in other countries). (Warning: Do not use a multimeter to measure the wall outlets in your home. This is very dangerous.) If you need to measure alternating current in a circuit, different multimeters have different symbols to measure it (and the corresponding voltage), usually "ACA" and "ACV," or "A" and "V" with a squiggly line () next to or above them. 2ff7e9595c
