Page 5: Introduction
PV is comparable to heating with traditional collectors, either flat plat or evacuated tubes. PVTHERM™, a product of Modulus Logistics, is a PV controller that converts the electrical power generated with photovoltaic panels and applies this power directly to the existing geyser element. -
Page 6: Safety Instructions & Warnings
PVTHERM: User Manual • Grid can be used for backup if required. • Even if the water pipes between a thermal collector and geyser are lagged, the thermal losses are still huge. The losses in the electrical cables (voltage drop) are minimal and therefore the panels can be far from the geyser, or even at a different floor level. -
Page 7: Transport And Storage
PVTHERM: User Manual • The product is a combination of a high voltage DC source and mains/grid AC source. Even if the equipment is switched off, a dangerous electrical voltage can occur at the input and/or output terminals of the inverter due to charged capacitors. -

Page 14: System Protection
• Separate earth connection onto unit • Anti-Islanding 05. Maintenance • PVTHERM™ does not require specific maintenance. • It will suffice to check all connections once a year. • Avoid moisture and oil/soot/vapours and keep the device clean. • PV modules should self-clean if the angle of installation is more than 10 degrees to the horizontal. -
