Solar and Wind Off Grid systems
PV Solar panel for solar off-grid and tied-grid systems
The batteries used to store solar and wind energy are currently mainly lead-acid batteries. Short lifespan and low cycle number of lead acid batteries make it a weak candidate for environment and cost efficiency.

Lithium-Ion batteries allow to equip solar or wind “off-grid” power stations, replacing the legacy banks of lead-acid batteries.

Benefits :

A lifetime (number of cycles) well above the lead-acid batteries (over 1500 cycles at 90% depth of discharge)
Footprint and weights 2-3 times lower than lead-acid
No maintenance required
Compatibility with installed equipment (charge controllers, AC converters, etc.) by using advanced BMS
Green solutions (non-toxic chemistries, recyclable batteries)

We offer flexible and modular solutions to meet all types of applications (voltage, capacity, sizing). The implementation of these batteries is simple and fast, with direct drop-in of legacy battery banks.

Major advantages of Lithium Iron Phosphate:

Very safe and secure technology (No Thermal Runaway)
Very low toxicity for environment (use of iron, graphite and phosphate)
Calendar life > 10 ans
Cycle life : from 2000 to several thousand (see chart below)
Operational temperature range :up to 70°C
Very low internal resistance. Stability or even decline over the cycles.
Constant power throughout the discharge range
Ease of recycling

Life-cycle ofLithium Iron Phosphate technology (LiFePO4)

Longer battery life, the life expectancy is two times that of lead-acid batteries.
Rechargeable and no memory effect.
The weight is more lighter.
Smaller dimensions and can be customized.
Safer and more environmentally friendly, No heavy metals and hazardous substances.
BMS built-in IC chip will prevent battery pack over charge, over discharge, over-current,
over-heat, short circuit .

In standard environment, and for 1C cycles, the below life cycle estimation for LFP :

2000 cycles at 100% DoD
3000 cycles at 80% DoD
8000 cycles at 55% DoD

Warnings

Do not immerse the battery in water or seawater, keep the battery stands by in a cool dry surrounding.
Does not use or leave the battery near a heat source as fire or heater.
Use the battery charger specifically for that purpose when recharging.
Do not reverse the position and negative terminals.
Do not connect the battery electrodes to an electrical outlet.
Do not discard the battery in fire or a heater.
Do not short-circuit the battery by directly connecting the positive and negative terminals with metal objects.
Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc.
Do not strike, trample or throw the battery.
Do not directly solder the battery and pierce the battery with a nail or other sharp objects.
