Compared with the previous RiiO Sun series, it boasts higher PV open circuit voltage, higher PV charging power and current. It is optional to work without battery and only use solar energy to power loads directly. You can start with the comprehensive system or a smaller solution and gradually expand it, depending on what best suits your needs and budget. A programmable smart port is also equipped in both 5kVA and 8kVA models for generator input or load management.
