Solar Panel Compatibility: A Plain Guide to Adding Solar to a Zeliox System
Can you add solar panels to a portable power system? How solar input works on Zeliox ECO SLIM, ECO II and NEO 4000, and how to size panels for your loads.
Campervan Electrical System Guide: Building out a Camping Electrical System
Building out a campervan electrical system? Space is tight, safety matters, and the last thing you want is a rats' nest of wiring behind your cabinets. This guide walks through the core components — battery, charging, inverter, distribution — and how to keep it clean, safe, and serviceable.
Caravan Power System Sizing Guide
Sizing a caravan power system isn't about picking the biggest battery you can afford. It's about matching your storage, solar, and charging to how you actually use power. This guide walks through the load audit, solar maths, and charging strategy that gets it right.
Common Myths About Portable Power Stations
Six common misunderstandings about portable power stations, with the practical checks to make before you choose or use one.
A Beginner's Guide to DC-DC Charging
DC-DC charging manages power from a vehicle’s alternator to an auxiliary battery. Here is where it fits, what it does and what to check.
Quick answers
All knowledge base →What does solar input mean?
Solar input is the electrical input through which a power system accepts energy from compatible solar panels. The input has voltage, current, power, connector and controller limits that the panel or array must meet.Read →What is a dual battery system?
A dual battery system adds an auxiliary battery to a vehicle's starter battery so work or camping loads can use stored energy without relying directly on the battery reserved for starting the engine.Read →What is Alternator Charging?
Alternator charging uses vehicle engine power to recharge an auxiliary battery while driving, usually through a DC-DC charger.Read →What is an auxiliary battery?
An auxiliary battery is a secondary battery used to supply accessories or work equipment separately from a vehicle's starter battery. It is commonly part of a dual battery or mobile power system.Read →What is an MPPT?
MPPT stands for maximum power point tracking. It is a control method used to help compatible solar systems draw useful power as conditions change.Read →What is battery capacity?
Battery capacity describes how much charge or energy a battery can store under stated conditions. For portable power, watt-hours or kilowatt-hours are the clearest starting point because they include both voltage and charge capacity.Read →What is DC-DC Charging?
DC-DC charging uses your alternator to charge an auxiliary battery at the right voltage. Here’s how it works in vehicle power systems.Read →What is Shore Power?
Shore power is 240V mains power supplied from a caravan park, marina, depot or workshop to run or recharge an onboard system.Read →What is the difference between AC and DC power?
Direct current (DC) flows in one direction and is used by batteries, solar panels and many vehicle circuits. Alternating current (AC) regularly reverses direction and is the form supplied through standard mains outlets.Read →
