Solar panels

4.1. General instruction
The solar panel should be put in direct sunlight, absolutely no part of it should be shaded, even partially. Ensure the panel is placed in a location where no shading will occur at any time during the day.
The solar panel should be cleaned regularly; the dust can have a significant impact on performance. It can be cleaned using a wet cloth or sponge.
The controller will operate only if the PV voltage exceeds the battery voltage (Vbat).

• PV voltage must exceed Vbat + 2V for the controller to start.
• Maximum open circuit PV voltage: 24V
  All panels connected on the SHS 200 must be identic with the exact same specifications.

4.2. PV connection
The SHS 200 exists in two different versions: barrel and MC4 connectors. The difference stands in the connectors used to plug PV panels. The SHS with barrel connectors is easier to install and more suitable for smaller PV arrays. The SHS with MC4 connectors enables to use of a larger range of PV panels which is useful for more powerful configurations.

know-how.

Possible PV panels combinations:

*No series connection allowed
4.2.1. Model with barrel PV connectors
The product includes 4 PV inputs (5.5mmx2.1mm barrel connectors). Each input can be connected to one solar panel comprising of 36 cells in series (“12V panel”) and with a maximum short-circuit current (Isc) of 5A. The overall total peak power installed on
the SHS must not exceed 200Wp (watts peak).

4.2.2. Model with MC4 PV connectors
The product includes a positive and a negative extension cable (25 cm length – 14 AWG section). The negative cable is terminated by a female MC4 connector. The positive cable is terminated by a male MC4 connector. It allows a correct connection with PV modules that generally have the female MC4 connector on the positive cable (male on the negative). Any combination of 36-cells panels connected in parallel with an overall total peak power of 200Wp (watts peak) or less can be installed on the PV terminals (e.g., 2 x 90Wp, 1 x 200Wp). It is recommended to use MC4 splitter connectors (also called Y or W connectors) to connect panels in parallel.

4.3. Sizing examples
The table below gives some examples of suitable PV panels and battery combinations for the SHS 200. Daily energy production is calculated for an average daily irradiation of 5000Wh/m²/d. Local conditions (solar irradiations and temperature) should be
considered for proper system sizing. Lower solar irradiations result in bigger PV power and battery capacity requirements to supply the same energy demand. Higher temperatures result in lower PV panels efficiency.

PAYGO FUNCTIONALLITY

7.1. General
The SHS 200 is a pay-as-you-go (PAYGo) enabled device. It allows end-users to digitally pay for energy through a pre-paid “rent-to-own” model.

1. The end-user pays energy to their distributors for a definite period of time (e.g. 30 days);
2. An activation token is sent by SMS to the end-user;
3. The end-user enters the activation token on the keypad of the SHS;
4. The SHS is unlocked (active DC outputs) and can be used until time credited is spent.
   Payments are usually done by mobile money or cash transfer to avoid cash collection and to allow automated processing. A PAYGo software platform enables distributors to generate and send activation tokens according to customer payments.
   It is also possible to use the SHS 200 without the PAYGo function. The device is simply active forever and does not require any token to be unlocked.

7.2. OpenPaygo token
The SHS 200 runs with the OpenPAYGO token. It is an open-source token system which can be integrated with any PAYGo software platform.
More information: https://enaccess.org/materials/openpaygotoken/
7.3. Compatible platforms
The SHS 200 is already integrated with the following commercially available PAYGo platforms:

• Angaza: https://www.angaza.com/
• PaygOps: https://www.paygops.com/
• Paygee: https://paygee.com/

7.4. Activation process
The activation menu is used to add time credit to the SHS. If the device is fully activated this menu is not useful. If the device is not activated (time is 0) the screen displays “Not Active”. The device can be activated with the following procedure:

1. Access the activation menu by pressing the LOCK button.
2. Enter the activation token provided by the PAYGo platform.
3. Press CHECK to validate. It should now show the number of days added.
   Press LOCK again to return to the main menu.

TROUBLESHOOTING

9.1. Error message
Below is an explanation of the reasons why a particular error message would be shown on the device screen. Alerts are critical issues, the device will try to auto-protect but the source of the issue should be removed before continuing using the device.
Warnings are less serious but can still require action to fix them.
9.1.1. Alerts:
Over Temperature:

• Using the SHS 200 in an overly hot place
• Using the SHS 200 directly exposed to sunlight
• Using the SHS 200 in a place with inadequate ventilation.

Battery Overvoltage:

• Connecting the solar panel (or another power source) on DC output port
• Using an incorrect battery type (for example a 12 cells battery instead of a 6 cells)
• Using a battery that has been overcharged before

Battery Overcurrent:

• Using too many appliances drawing too much power at the same time (more than safe for use with the selected battery).
• Connecting the solar panel (or another power source) to the DC output port

USB Overcurrent:

• Using USB appliances that exceeds the maximum current supported by the port.

DC12 Overcurrent:

• Using DC appliances that exceeds the maximum current supported by the port.

9.1.2. Warnings:
Panel OverVoltage:

• Using a solar panel that is inadequate for use with the SHS 200 (for example a 60 cells solar panel instead of 36 cells)
• Using a power source that is not a solar panel and that has a voltage that is too high
• Using an approved solar panel, but in a situation with very low outside temperature (close to 0 degrees Celsius) can cause the panel to produce an overly high voltage.

Battery UnderVoltage:

• Using an overly discharged battery (well below the low battery cut voltage)
• Using an incorrect battery type (for example with 2 cells instead of 6 cells)

9.2. Device not active
If the device is showing “Not Active, Please Activate”, it means that the device should be activated. To do so press the (LOCK) key to access the Activation Menu and follow the procedure described in the section Activation process.
9.3. Low battery
If the device screen shows “Low Bat.” and the USB ports and lights are turned OFF, it means that the battery is discharged, and the device is preventing further use of it to avoid damages.
This can happen in case of overuse or in case of low amount of incoming solar power (cloudy weather or poorly positioned solar panel). Check that the solar panel is positioned in full sun and allow the battery to charge without using the device for a couple of
daylight hours and then use it as little as possible until the battery reaches a high state of charge (over 80% after the charge is finished at night). Do not in any case try to connect anything directly to the battery to bypass that protection as it will permanently damage the battery.
If the weather is good and the usage is low, the problem might come from the solar panel, in that case, refer to the section below for further information on how to solve the problem.
9.4. Solar panel level always low
If the solar panel indicator is low (below 40%) even when there is a lot of sun shining on the solar panels or if the battery never reaches a high level of charge, there might be an issue with the solar panel positioning or cleanliness.
First, check if the solar panel is cleaned. A thin layer of dust or a small (even just 1cm wide) piece of dirt or leaves on the panel can significantly impact its performance. Use a wet cloth to clean the panel thoroughly.
Second, make sure that no part of the solar panel is in the shade, a small shadow on any part of the solar panel can reduce its production a lot. Make sure that no tree, branch or construction will make a shadow on the solar panel at any time of the day.
