3.5kVA Family Kit
Mid-range hybrid solar system sized for urban and semi-urban family homes. Supports a 12V fridge, multiple fans, lighting and entertainment loads with 2.4kWp generation and 4.8kWh of LiFePO4 storage for overnight backup.
High-demand kit for South Africa load-shedding resilience and Nigerian urban distributors. The 4.8kWh battery covers 6–8 hours of grid outage for a typical family home without running the generator.

Frequently Asked Questions
Will a 3.5kVA solar kit run a fridge continuously through the night?
Yes. The 4.8kWh LiFePO4 battery is sized to cover overnight fridge operation (80W average × 10h = 800Wh) plus lights and fans. At 80% DoD the battery delivers 3.84kWh usable, which covers typical overnight loads with margin. For households with two fridges, we recommend upgrading to the 5kVA kit with 9.6kWh storage.
What is the MOQ and lead time for 3.5kVA solar kits?
Minimum order is 5 systems for a standard production run. Mixed orders combining 3.5kVA and 5kVA kits are accepted from 10 units total. Standard production and testing lead time is 20–25 business days. Samples (1 unit) can be arranged in 10–14 business days.
Can I brand the 3.5kVA kit with my company name?
Yes. OEM white-label is available from 20 units. Inverter LCD panel stickers, battery enclosure labels and carton printing can all carry your brand. No tooling charges for label-based OEM. Lead time for branded production is 25–30 business days including label approval.
