When connecting solar panel and batteries, it is best to use a kaiwhakahaere utu solar, ka taea te whakahaere i te ngaohiko whakaputa o te hiko o te ra, te tiaki i te pākahiko mai i te nui o te utu, i te wa ano, i te po ano kaore te hiko o te ra e whakaputa hiko, kia kore ai e hoki mai te hiko o te pākahiko.

To hook up a solar panel to a battery, follow these organized steps to ensure safety and efficiency:
Wae e hiahiatia ana
-
Pae Rahera: Voltage compatible with your battery (e.g., 18V panel for a 12V battery).
-
Kaiwhakarato Tiaki: PWM (for simple setups) or MPPT (for higher efficiency, especially with higher voltage panels).
-
pūhiko: Ensure type (lead-acid, lithium, etc.) matches the controller’s settings.
-
Waea me nga Kaihono: Correct gauge for current; MC4 connectors for panels if needed.
-
Fuses/Circuit Breakers: Sized for system current (e.g., 20-30A for a 100W panel).
-
Utauta: Multimeter, crimping tool, screwdrivers.
Aratohu Taahiraa-i te-Hipanga
-
Haumaru Tuatahi
-
Wear insulated gloves and safety glasses.
-
Disconnect all components before wiring.
-
-
Maungahia te Paewhiri Solar
-
Install in a sunny location, angled optimally (often latitude + 15°). For more information, you can check out our guide to the best solar panel angles

-
Honoa te Kaiwhakahaere Utu ki te Pūhiko
-
Order Matters: Connect battery first to initialize the controller.
-
Use proper wire gauge (e.g., 10 AWG for 20A current).
-
Pūrongo: Attach battery’s (+) to controller’s BAT+ and (-) to BAT-.
-
Fuse: Add an inline fuse on the positive wire near the battery (e.g., 20A for a 12V/100W system).
-
-
Configure the Charge Controller
-
Set battery type (flooded, AGM, lithium) via dip switches or menu.
-
-
Honoa te Paewhiri Solar ki te Kaiwhakahaere Utu
-
Use MC4 connectors or adapters if needed.
-
Pūrongo: Panel’s (+) to controller’s PV+ and (-) to PV-.
-
Fuse: Add a fuse between panel and controller (sized to panel’s max current).
-
-
Ground the System (Optional but Recommended)
-
Ground the solar panel frame and charge controller to prevent surges.
-
-
Whakamatauhia te punaha
-
Use a multimeter to check voltages:
-
Panel’s open-circuit voltage (should match specs).
-
Battery voltage (should rise when charging).
-
-
Verify controller indicators show charging.
-
-
Add an Inverter (Optional)
-
Connect an inverter to the battery for AC power needs.
-
Te Whakaaroaro Nui
-
Mata Gauge: Thicker wires for longer runs/higher current (e.g., 10 AWG for 10A over 10ft).
-
Momotu Whakawhiti: Install for easy maintenance.
-
Pukapuka Kaiwhakahaere: Follow manufacturer instructions for settings and limits.
Nga Hapa Ngatahi hei Ape
-
Reversing polarity (double-check connections).
-
Skipping fuses (risk of fire or damage).
-
Connecting solar panel before battery (may damage the controller).
By following these steps, you’ll create a safe and efficient solar charging system. Always refer to component manuals for specific details.
