AndSolar rapid shutdown devices and optimizers

Q: What is rapid shutdown and why have it?

Solar panels keep making high-voltage DC whenever the sun is out; even with the inverter off, the roof's panel cables still carry hundreds of volts. Rapid shutdown devices sit under the panels and cut them one by one. Press the emergency switch or use the app and the panel strings drop below 30 V within 30 s. That makes the roof safer for firefighters and technicians (NEC 690.12).

Q: AMCL or AMCP: what is the difference?

- AMCL-E2 (rapid shutdown): module-level shutdown and per-panel data · AMCP1200-1500 (optimizer): the same, plus more power from shaded or mixed-direction panels, up to 1,500 W per pair An unshaded roof can use the AMCL; a shaded or multi-direction roof suits the AMCP. The team can tell from site photos.

Q: Do I need the ADCU-M0 gateway? What do (10) and (30) mean?

Every system needs one ADCU-M0: it sends the shutdown signal and the per-panel data to the app. · (10): one ring, 10 strings, 200 panels · (30): two rings, 30 strings, 600 panels (Panel counts with one device per 2 panels.)

Q: Which inverters does it work with?

The maker says it works with most mainstream inverters. The team checks the inverter, panels and string voltage before every installation. Ask on LINE.

Q: How long is the AndSolar warranty?

The maker's documents do not state a warranty period. Ask the TAMNIYOM team on LINE for the period and terms.

FAQ

Questions about AndSolar

What is rapid shutdown and why have it?

Solar panels keep making high-voltage DC whenever the sun is out; even with the inverter off, the roof's panel cables still carry hundreds of volts.

Rapid shutdown devices sit under the panels and cut them one by one. Press the emergency switch or use the app and the panel strings drop below 30 V within 30 s.

That makes the roof safer for firefighters and technicians (NEC 690.12).

AMCL or AMCP: what is the difference?

AMCL-E2 (rapid shutdown): module-level shutdown and per-panel data
AMCP1200-1500 (optimizer): the same, plus more power from shaded or mixed-direction panels, up to 1,500 W per pair

An unshaded roof can use the AMCL; a shaded or multi-direction roof suits the AMCP. The team can tell from site photos.

Do I need the ADCU-M0 gateway? What do (10) and (30) mean?

Every system needs one ADCU-M0: it sends the shutdown signal and the per-panel data to the app.

(10): one ring, 10 strings, 200 panels
(30): two rings, 30 strings, 600 panels

(Panel counts with one device per 2 panels.)

Which inverters does it work with?

The maker says it works with most mainstream inverters.

The team checks the inverter, panels and string voltage before every installation. Ask on LINE.

How long is the AndSolar warranty?

The maker's documents do not state a warranty period. Ask the TAMNIYOM team on LINE for the period and terms.
