THE SMART CHOICE

This smart solar solution generates power from both the front and back, making the most of sunlight, even the light that reflects off the ground.

Perfect for floor or adjustable mounting systems where you can really take advantage of that extra energy.

CHARGE FASTER

TOPCon N-Type cells use advanced solar tech to give you more power from the same amount of sunlight, so your batteries charge faster, even when the sunlight isn’t perfect.

Each cell has a special tunnel layer that helps electrons flow more efficiently, and a retention layer that reduces energy loss. That means more of the sunlight gets turned into usable electricity, even when it’s cloudy, early in the morning, or late in the day.

N-Type cells are also more stable over time and don’t degrade as quickly as older types, so your panels will keep performing well for decades.

RELIABLE IN LOW LIGHT

Thanks to advanced N-Type TOPCon cells, Voltanics panels can still produce energy even when the sun isn’t shining brightly, like on cloudy days, in the early morning, or late afternoon. So you get more power throughout the day, no matter the weather.

EASY TO INSTALL

Pre-drilled mounting holes to fit a variety of mounting systems, along with MC4 connectors for easy wiring and a strong, built-to-last design.

MORE POWER GENERATION

With 16-busbar (16BB) technology, Voltanics panels deliver improved energy efficiency and reduce microcrack risks, ensuring longer lifespan and consistent performance.

READY FOR THE OUTDOORS

Optimal performance in heavy rain, dust, and all weather conditions for a long-lasting solar setup.

WARRANTY-BACKED & CERTIFIED

With Voltanic, beauty and efficiency aren’t just a first impression; they’re a lasting commitment. A robust warranty backs every panel, ensuring that even after 30 years, your panels will still be generating energy.

FAQ

How long will a 100Ah lithium leisure battery last?

A 12V 100Ah LiFePO4 leisure battery gives you roughly 1200 usable watt-hours of energy (12V × 100Ah = 1200Wh). To figure out how long it will run for, simply add up the watts of all your devices and divide 1200 by that number.

General Guideline:

100W usage (small TV, lights): ~12 hours
200W usage (TV, laptop, lights): ~6 hours
500W usage (small heater): ~2.4 hours
1000W usage (microwave, kettle): ~1.2 hours

Remember: Actual runtime will vary based on temperature, battery age, and the type of devices being powered.

How many solar panels to charge a 100ah battery?

Using the Voltanic 200W Solar Panel as an example, the module itself generates around 10 amps per hour in peak sunlight. Since a 100Ah battery needs 100 amp-hours to charge fully, it would theoretically take 10 hours of perfect sunlight to charge it up. However, you typically only get 4-6 hours of good sun per day (in the spring & summer), so expect about 2 days for a full charge with a 200W panel.

General Guide:

Basic setup: 200W panel (2-3 days to charge)
Better setup: 300W panel (1-2 days to charge)
Optimal setup: 400W+ panel (1 day to charge)

Remember: Always use an MPPT solar charge controller between your panels and battery if you want to generate the most power.

How long will a 12V fridge run on a 100Ah battery?

A typical 12V camping fridge uses around 2-4 amps per hour (24-48 watts) when the compressor is running. However, fridges don’t run constantly – they typically cycle on and off to maintain temperature, running about 30% of the time in normal conditions. This means they average 0.6-1.2 amps per hour (7-14 watts).

Runtime Guideline:

Average conditions: 3-4 days runtime
Hot weather (more cycling): 2-3 days runtime
If running constantly: 20-30 hours

Remember: These are estimates – actual runtime depends on ambient temperature, how often you open the fridge, how full the fridge is etc.

What size inverter do I need for my 100ah battery?

The key factor to look at is your battery’s continuous discharge current rating. This is the amount of current (or amps) the battery can safely discharge continuously during day to day usage. A typical 12V 100Ah LiFePO4 battery has a continuous discharge rating of 100A or 1200 Watts (100A × 12V = 1200W)

Therefore, you should not use devices that continuously draw more than 1200 watts making the 1200W inverter perfect.

Note: You can technically use larger 1500-2000 watt inverters on a 12V 100Ah battery as running an inverter at 50-60% capacity (rather than at full load) can actually extend its lifespan. Just remember to never use devices that breach the continuous discharge current limit or you will reduce the lifespan of your battery & could damage it.

Remember: Always choose a pure sine wave inverter.

Can I use my lead-acid charger to charge my LiFePO4?

Yes, most standard 12V lead-acid chargers can safely charge LiFePO4 batteries since they charge at similar voltages (around 14.4V). However, there are a few things to consider:

Good to know:

Lead-acid chargers typically charge at lower currents, so charging will be slower
You may not achieve 100% charge
Avoid chargers with “desulfation” or “recovery” modes that use high voltage

For best results:

Use a proper LiFePO4 charger for faster charging and optimal battery life
If using a lead-acid charger, make sure it doesn’t exceed 14.6V
Check that your charger doesn’t have aggressive equalization modes

Remember: While lead-acid chargers will work, a dedicated LiFePO4 charger is a better long-term investment for optimal battery performance and lifespan.

How to recharge my LiFePO4 batteries?

LiFePO4 batteries require a specific charging profile to ensure safe, efficient charging and maximum battery life. You have several charging options:

LiFePO4 Battery Charger (Wall Outlet)
Solar Panels
Use a DC-DC charger designed for LiFePO4

Remember: Always match charging voltage (14.4V-14.6V)

Can I use a split charge relay to charge my LiFePO4 battery?

Technically yes, a split charge relay could work to charge a LiFePO4 battery since alternators typically output 14.4V, which is within LiFePO4’s charging voltage range. However, it’s not recommended because:

Alternator voltage can spike and fluctuate (especially in modern vehicles)
No protection against overcharging
No temperature monitoring
Could potentially void battery warranty
May cause premature battery wear

Better solution:

Use a DC-to-DC charger designed for LiFePO4
Provides proper voltage regulation
Includes safety features and proper charging profile

While a split charge relay might work in a pinch, investing in a proper DC-to-DC charger will protect your battery investment and ensure safe, efficient charging.
