Description
x16kW Off-Grid Solar Kit – 20kWh Pylontech US5000, 20x JA Solar 465W Panels
This complete off-grid solar kit is built around two parallel Conversol MAX 8kW inverter-chargers and four Pylontech US5000 lithium batteries providing 20kWh of usable storage. Twenty JA Solar 465W monocrystalline panels deliver 9,300W of PV capacity, with the system able to accept up to 40 panels (18,600W) for future expansion. The kit is designed for domestic and commercial properties requiring continuous off-grid power or grid-backup capability.

Product Overview
The system is designed to power domestic and commercial single phase loads continuously, with a peak output of 16kW sufficient for most 2 to 4 bedroom residential properties and many small commercial premises. The two parallel Conversol MAX inverters provide both the power capacity and redundancy required for 24/7 operation.
With an AC charge timer built into the inverter, the battery bank can be topped up from the grid at low-cost overnight tariff rates when solar generation is insufficient. The system can operate with grid backup, generator backup, or fully off-grid depending on site requirements.
The Solar Assistant monitoring kit stores performance data on an internal SD card for up to 10 years and provides remote monitoring via Wi-Fi at no ongoing cost. It is supplied pre-configured and ready to connect.
Solar panels are supplied with a triangular adjustable mounting structure suitable for flat surface and ground installations. Alternative mounting options are available on request at no extra cost.
