RV Power Comparisons

12V vs 24V System

At 24V the same power moves at half the current and voltage drop falls by a factor of four. Here is when that actually matters for

30A vs 50A Service

30 amp vs 50 amp RV shore power service compared by actual available watts, why an adapter never adds amperage, and how to size lo

ANL vs Class T fuse

ANL fuses handle most RV lead-acid and single-battery lithium banks. Large LiFePO4 banks need a Class T fuse, which carries a much

DC-DC charger vs isolator/VSR

A VSR connects banks directly and can work on lead-acid. On a lithium house bank it is dangerous, because LiFePO4 will accept near

Generator vs Solar

Solar is silent and free to run but only works in sun. A generator works at night and is the only realistic way to run RV air cond

Inverter vs Inverter/Charger

Plain inverter vs inverter/charger for RV power systems compared on cost, install complexity, transfer switching and when a separa

Cost per cycle: lead-acid vs lithium

Lithium costs more upfront, but published cycle life and usable depth of discharge change the real per-cycle math. Here is what is

LiFePO4 vs AGM

LiFePO4 vs AGM for an RV house battery compared on usable capacity, weight, cycle life, cold-weather charging and real cost per us

MPPT vs PWM

MPPT vs PWM RV solar charge controllers compared on harvest gain, cost, panel voltage matching and the exact setups where PWM is g

Pure Sine vs Modified Sine

Pure sine vs modified sine RV inverters compared on what each waveform actually does to motors and electronics, and why one is use

Rooftop vs Portable Solar

A rooftop array needs no setup but cannot be aimed or moved out of shade. A portable panel can chase the sun. Here is which fits y

Converter vs Inverter/Charger

A converter only charges your 12V bank from shore power. An inverter/charger also inverts and switches automatically. Here is who

Self-Heating vs Standard LiFePO4

Charging LiFePO4 below freezing causes permanent damage. Self-heating batteries warm cells first. If you never camp below freezing

Series vs parallel wiring

Parallel wiring adds capacity at the same voltage; series wiring adds voltage at the same capacity. Get the interconnect cables wr

Shunt vs voltmeter

A shunt monitor counts amp-hours; a voltmeter reads volts. On LiFePO4 that difference decides whether you know your real state of

Soft starter vs bigger generator

A soft starter cuts AC compressor inrush for a fraction of what a larger generator costs, often dropping the generator size you ne

Solar vs Alternator

Solar vs alternator charging for RV lithium and lead-acid battery banks, including why a DC-DC charger is required and why most go

Surge Protector vs EMS

A plain surge protector only stops a spike. An EMS also cuts power on low voltage, high voltage, open ground, and reverse polarity
