Safari Camp – 60kWp

This 60kWp solar array is connected to Fronius 20kVA grid-tied inverters and Victron Quattro units. At the heart of the system is a 195kWh Blue Nova lithium ion battery bank.

4kWp off-grid

This off-grid system provides all the power needed for a remote anti-poaching unit in the Okavango Delta – with a 16kWh Blue Nova battery and two 3kVA Victron Multiplus units. It also has a remote monitoring system to allow offsite monitoring – for a taste of what this can provide click here.

Lithium ion upgrade: Blue Nova 16kWh

IMG_6410.JPG

We used a 16kWh 52V (310Ah) Blue Nova lithium ion battery to replace a 900Ah lead acid battery bank. So far, the change has been dramatic, with the batteries getting to a 100% SOC on a daily basis despite cloudy weather – mainly due to the efficiency (96%) of the lithium ion system compared to 70% of a lead acid battery.


Blue Nova Retrofit – 32kWh

We replaced an ailing lead acid battery bank with a two new Blue Nova 52V 16kWh lithium ion batteries for a 32kWh system. The original bank was a 76kWh bank with 24 x 2V 1600Ah lead acid batteries.

Work in progress – busy installing and programming the new 32kWh system


Residential 1.5kWp (upgradable to 2kWp)

This small 1.5kWp residential system has a 20kWh lead acid battery system and 3kW inverter to cope with fridges and power tools (occasional use). We’ve allowed for an additional 750Wp of solar for future needs.


Residential 3kWp

This residential installation has just had a 16kWh lithium battery bank installed

Update: March 2018 – we’ve now added another 4 panels, pushing this to 3kWp


Safari Camp in the Okavango Delta

Each of the tents have a 200L solar geyser and a 500Wp solar system with a 800W Victron Phoenix inverter housed in a lockable and weatherproof enclosure.
