It’s a low-voltage DC power system, typically used in vehicles and off-grid setups to power lights, fridges, pumps, and more.d an answer to this item.
Only if you have an inverter to convert 12V DC to 240V AC — but it uses more power, so pick your appliances wisely.
AC (like in your house) flows back and forth. DC (like in vehicles) flows in one direction — 12V systems are DC.
Add up the watts of all devices × hours used per day ÷ 12 = amp-hours (Ah). Add a safety buffer too.
Lithium is lighter, lasts longer, and charges faster — but it's more expensive upfront. AGM is cheaper but heavier and has less usable power.
With a solar panel, DC-DC charger (from your alternator), or an AC charger from mains power.
Yes. Every circuit should have a fuse close to the power source to protect against shorts and fire.
Use thicker cable for longer runs or higher amps to reduce voltage drop. Undersized cable = heat + wasted power.
It’s the loss of voltage across a cable. Too much drop means poor performance or damage to gear. Keep it under 3-5%.
Yes — just make sure the battery has enough capacity to last through the night, and it’s recharged daily.

It boosts and regulates charging from your vehicle's alternator to your second battery, especially important for smart alternators.
Yes. It protects your battery from overcharging and controls the voltage coming from your solar panel.
MPPT is more efficient, especially in cloudy or varied light — it gets more juice from your panels.
Not a good idea. Each type charges differently — mixing them can cause damage or poor performance.

Could be overused, undercharged, old, or a parasitic drain somewhere. Time for a load test and inspection.
Only with a big enough inverter (2000W+), a large battery bank, and ideally lithium. These appliances chew power fast.
Only if you want to run 240V appliances. Otherwise, stick to 12V gear and avoid the power loss.
It measures current in/out of your battery and shows real-time stats — like a fuel gauge for your system.
It can be if done wrong — always use proper fuses, correct wiring, and follow safety rules. Or call us if unsure!
