The six absolutes
- Three sources, always assume live. PV makes voltage in any daylight, the battery is always ready, and the grid can return without warning. Isolation means all three — see Isolation & Shutdown.
- Stored energy after switch-off. The inverter holds residual voltage after powering off and needs 5 minutes to discharge — wait the full 5 minutes before opening any cover.
- Never break DC under load. Do not unplug PV or battery connectors while current flows; shut the inverter down and isolate in sequence first. DC isolators are not load-break switches unless rated for it.
- Hot surfaces. The unit runs hot in operation — the Kent G3 heat-sink can reach 75 °C. No touching in operation, no combustibles nearby.
- No cover, no exceptions. There are no user-serviceable parts inside; covers come off only for Kent-authorized work after full isolation and the discharge wait.
- PPE on, metal off. Personal protective equipment through the entire job; watches and rings off for battery work — see PPE & Tools.
Before you start any job
- You are trained and authorized for this platform (Kent M1 and Kent G3 differ).
- You have this knowledge base or the printed pack for the exact model on site.
- Your meter, clamp ammeter and PPE are present and working.
- Someone responsible on site knows you are working on the system.
Common mistakes
- Trusting a dark display as “dead” — capacitors do not care what the screen shows.
- Working the DC side because “it’s only 50 volts” — battery DC at these currents welds tools and starts fires.
- Letting an unqualified helper make connections while you supervise from a distance.
When to escalate
Escalate to Kent New Energy service only — through your registered Kent partner channel or the Kent service desk details on your work order. Do not contact any third-party or component-manufacturer support line for a Kent-branded system: tickets outside the Kent channel are not tracked, not covered, and can void warranty handling.
