8kW Off-Grid System | SMA and Li-ion Batteries

Category: Tags: ,

Description

This large off-grid system is designed to be efficient and perfectly sized for big households that would cycle their battery often.

With 30 x solar PV modules, this 8kW system will generate 22.4-27.2kWh of power per day. This system size is great for those with heavy energy usage, and those who wish to keep their batteries topped up.

The SMA inverter is a high-quality inverter with excellent surge ratings. The SMA can be configured to meet many off-grid system’s needs and will maintain it’s high performance even under the harshest environmental conditions. When setting up in an off-grid system, power will first be drawn from the inverter, and then the batteries. Allowing the homeowner to get the most from their solar energy production.

Lithium-ion batteries offer the longest lifespan at 6000 cycles. Not only that, but their rated depth-of-discharge is much higher. Unlike AGM and gel batteries that only discharge to 50%, Li-ion batteries discharge to up to 90%. Which means the usable capacity per cycle is greatly increased. This is the most premium choice for a battery and is fit for a more power-hungry household, or one that prioritises longevity over costs in their system.
