a.) Check for any missing or wrong parts from the solar system and accessories.
b.) Check for any physical damage, scratches, bumps, cracks on all parts of the products and accessories. Check the wire, any bending/broken traces near the plug, wire damaged due to strong force.
c.) Check any dirt, rust, water, oxidation on all parts - check all cables, connections, sockets, plugs, switches, solar cable. Any water immersion, oxidation?
2.) GOOD Component Comparison
The easiest way to see if any component of a product has an issue is to replace it with a new component and see if performance is different or not.
For example if solar performance not as expected try with a new solar panel and see if different. Or if TV reception not as expected try with a different TV with same antenna and at same location and see if reception better or same.
3.) Solar charge issue?
a.) How to know sun is strong enough?
Adjust the solar panel until all 3x green LEDs of the solar indicator show up. Only if this is the case ALL day long we can call it a sunny day (>80.000 Lux). Only first 2 minutes after connection of the plug the indicator shows up.
b.) Solar Socket
Only the left most socket can be used for solar charging.
c.) Solar cable
Check cable of the solar module and observe if there is any physical damage.
4.) How to see solar charged 100%?
Only when all 3x battery LEDs are blinking the battery is fully charged.
3x Solar LEDs Solid = Good Sunshine
3x Battery LEDs BLINKING = Battery 100% FULL
3x Battery LEDs BLINKING = Battery 100% FULL
4.) Battery performance not as expected?
Place the solar panel under strong sun light to charge the battery for a whole day from early morning to evening until you see all 3 green LED of the battery indicator BLINKING. Before they „blink“ the product is not fully charged yet.
Now do runtime test: For 128Wh battery, it supports 3 NIWA lamps of 300 lumens for 16 hours lighting while it is 10 hours for a 84Wh battery and 5 hours for a 42Wh battery.
For all tests make sure no other appliances like phones, radios, TVs or fans connected.
5.) Battery indicator not accurate?
Battery Indicator need 3-4 charge/discharge cycles to be accurate. But one indication works very accurate from the start = 3-green battery LED BLINKING = 100% battery full.
After 2 full charging and discharging cycles completed, the battery indicator is accurate as below:
1-red LED blinking = < 10%
1-red LED = 11-24%
1-green LED = 25-49%
2-green LED = 50-84%
3-green LED = 85-99%
3-green LED blinking = 100%
5.) 5V USB or USB+ socket not working?
- PAYGO account not activated / not enough credits
Please check if a red LED of PAYGO indicator lights up. It indicates that either the PAYGO account is not activated or the account has not enough credit.
- Mobile adaptor check
use only the original NIWA mobile phone adaptor for charging.
Check the wire or cable of the mobile phone adaptor and observe if there is any physical damage on the wire.
- Try another 2 to 3 mobile phones and see if they can be charged.
The USB+ socket is not applicable to old mobile phones and there for fast smart phone charging.
Keep in mind to not charge too many cell phones at the same time.
6.) 12V output socket issue?
- PAYGO account not activated / not enough credit. Check if a red LED of PAYGO indicator lights up. It indicates that either the PAYGO account is not activated or the account has not enough credit.
- There are in total FOUR 12V sockets next to the solar charge socket. DO NOT use solar charge socket as 12V socket.
- Please check the wire or cable of the appliance you are trying to use and observe if there is any physical damage on the wire. Try with a new set of cables.
- check the output loading of the connected devices - does it match the rating label? NIWA solar system is designed for NIWA lamps, normal mobile phone, NIWA TV and NIWA fan. Please ensure not to connect too many appliances at once. If the power output is bigger than the rated power, the battery protects itself and blocks the power supply.
7.) Lamp not working
Please check the wire or cable of the lamp and observe if there is any physical damage on the wire.
Replace with a GOOD Lamp and see if the lamp can be turned on. If the LED of the battery indicator is on, it indicates that the unit is in good condition and the lamp could be defective.
8.) PAYGO issue
- Remote control check
Please check if there is any physical damage to the surface of the remote control. Press any button of the remote control, a blue LED light of PAYGO indicator is observed at each entry. It indicates that the battery could receive signal from the remote control. Try every button on the remote control if necessary. Please ensure plastic strip of the battery of the remote control is removed before the first use.
- Test Code: Verify if the unit can accept demo-code by entering * 406 4983 #. A blue LED light of PAYGO indicator is observed at each entry and six long blue LED lights of PAYGO indicator appear if the code is entered correctly. Then, the LED light of PAYGO turns off and you can connect a lamp to check if there is any output.
- If blue LED light is not observed, please try to exchange battery of the remote control and see if it works again.
Replace with E.) GOOD Remote control and see if the battery could receive signal from the remote control. If a blue LED of the PAYGO indicator blinks, it indicates that the original remote control could be defective.
- PAYGO account not activated yet
Please check at the Angaza platform to check if the account has been registered and activated. If yes, a 14 digits code should be generated. Please confirm if the code is inputted correctly with * at the beginning and # at the end. A blue LED light of PAYGO indicator is observed at each entry. If not, please contact Angaza for technical support.
Please check if there is enough credit in the account and contact end user to recharge the account accordingly.
