What is the difference between a 12V, 24V, 48V solar System?
The main difference is the size of loads you need to run. Running a couple of 15a(AC) 120v loads means > 300a(DC) on a 12v system, requiring heavy wire etc., which gets pretty impractical. Running on a 48v system the same loads would be 1/4 the amps, so ~75adc. A 12v system would also require 4x the charge controller capacity.
Need ideas on cistern pump with 12v solar system
Re: Need ideas on cistern pump with 12v solar system Ok so it lookls like #6 gauge and a shurflow is the best bet then.. this way I dont have to get a bigger inverter than the 1500 watt I plan on buying and already have 2/0 cables for..
Can I use a 12v inverter with a 24v setup? - northernarizona …
Re: Can I use a 12v inverter with a 24v setup? yes, certainly not worthless. i have 12v run out to my office and have the plug split into a 3 cig lighter config: one is a 300w modsine iverter for my camera and cell phone charging, the other is a 12v standard battery charger, the other 12v plug is for running the pc. this all works great at max ...

Can I Use 24v Panels on a 12v System - northernarizona-windandsun
Re: Can I Use 24v Panels on a 12v System My cousin has similar at his camp. Two 37 volt panels, and since they are roughly 200 feet from the camp, wired them in series, doubling the voltage to his TS-MPPT-60 which then dumps into his two L-16 batteries. (12 volt system) Works very well for him.

How Many 12v Solar Panels Needed To Charge 24v Battery?
2017年9月5日 · Re: How Many 12v Solar Panels Needed To Charge 24v Battery? The Amp hour capacity of the battery determines how much you need in Watts for proper recharging: V * A = W So a 12 Volt, 35 Amp hour battery would be recharged at (minimally) 14.2 Volts * 1.75 Amps = 24.85 Watts. Now, panels don't actually put out their "nameplate" rating all the time ...
wiring 12v solar panels to charge 24v - northernarizona-windandsun
The smallest to largest (cost effective array) using our rules of thumb for a solar PV powered off grid system (assuming you want most of your power from solar) would be: 29 volts charging * 250 AH * 1/0.77 panel+controller derating * 0.05 rate of charge = 471 Watt array minimum
12V load on a 48V system - northernarizona-windandsun
Re: 12V load on a 48V system using the 120vac inverted power to operate a 3 stage charger to a dedicated 12v battery may be one way and would keep the main battery bank operating in balance. the 48v-12v converter is far more efficient and skips wasteful steps and costs far less than all of the components needed for a dedicated battery with ac charger from an inverter. sometimes people have ...
