Data logger cover with integrated solar panel and charger

The RS-COVER-PV is a power provision cover fitting our RS-525SE/PE off-grid LTE-m & NB-IoT data logger. The cover has an ETFE sheet protected 1Wp 12-cell integrated solar panel, charger and a 26650 LiFeP04 battery holder.

This power provision is very convenient as it keeps the form factor and the complexity of your installation low. There is no need for an external solar panel, charger, battery, wiring or encapsulating cabinet.

LiFePO4 is a stable and safe battery chemistry with an excellent cycle life (over 1000 cycles at 100% DOD and thousands at 80% DOD). The energy round trip efficiency is much better than that of NiMH or Lead Acid batteries, so you can yield more energy from a same sized solar panel.

The PV-cells are encapsulated in ETFE sheet, which is the perfect material as it is heat resistant (up to 150°C) and does not deteriorate by UV-rays (UV-rays are passed through and contribute to the energy harvesting). The PV-cover is rather maintenance free as the ETFE surface is non-sticky and therefor self-cleaning (dust is easily blown off by wind and dirt washed away by a rain shower).

Additional instructions

Protective cap for the batteries

The battery holder can be fitted with a protective cap serving two purposes:

1) When subjected to heavy vibrations or sudden impact the battery can, due to its weight and despite of the relative high clamping force, dislodge from its holder. Mounting the battery cap minimizes the risk of a dislodging battery.

2) When using inferior or bad batteries, there could be a risk that in time these batteries are starting to leak and spray acid content.

Pole mounting kit

For optimum power yield, the solar panel should face the sun. Using our pole-mounting bracket, you can install it on a ground pole or on a wall/bridge-mounted pole, allowing you to orient the panel in the optimum direction.
