Installation tips

• Place a fuse (e.g. 3-5 A) as close as possible to the battery at the input.
• Avoid polarity errors; use wires of the correct cross-section.
• Fix to a surface to be cooled; do not conceal in heat retaining housings.
• If you are powering sensitive appliances, you can add a 12 V fuse and additional filtering.

FAQ

Is it suitable for a 72 V (20s) Li-ion system?
Yes – input range up to 84 V. Check that the fully charged voltage is within the limit.

Can I connect 12 V LED strips directly?
Yes, if the total power ≤ 60 W (5 A). A higher load requires a more powerful inverter.

Does the inverter charge a 12 V battery?
No – it’s a stabiliser, not a charger. A 12 V battery needs a suitable charger.

Stable 12 V / 5 A from a 20-84 V battery. IP67, up to 60 W. Suitable for 36/48/60/72 V systems – lights, horn, accessories.
