Overload

• Inverter Basics
• Inverter Issues

---

Basic Checks

1. Due to overheating due to fan fault
2. If fan is ok then check thermostat, resistor, diode and IC of the thermostat
3. Also check the 28 pin main inverter IC
4. Switch off and on inverter again+Disconnect battery wires and reconnect again tightly (low battery may be due to loose wires)
5. Check PCB Transformer
6. Wrong phase from stabilizer  – by changing the polarity the overload problem might solve
7. Incoming phase in inverter output wire due to wrong installation also cause the overloading problem. Just rectify the home inverter wire for phase leakage from the main line and the problem will be solved. Video.
8. If 83202 IC becomes faulty then also overload error occurs.

Luminous Ecowatt

Problem	Overload
Fault	Faulty LM358 IC and a resistance near LM 358 on checking.
Solution	Overload comes from two reason in this pCB LM358 IC Changed 1KOhm resistance near LM358 changed
Parts used	LM358 IC 1KOhm resistance near LM358

1. Exchanging Drain wires sometimes the drain wires gets exchaged and the error of overloading arises. Just exchange the drain wires and try to restart the inverter. Video.

Case 1

1. Due to fan issue – please check the point no 2 of the continuous fan run problem section. Video.

Case 2

Problem	Overload and No charging
Fault	Blown Mosfet Blown SMD Transistors Blown Gate resistors Incorrect drive from LM305 IC to the mosfet
Solution	Changed Blown Mosfet Blown SMD Transistors Blown Gate resistors LM305 IC
Parts used	unknown SMD Transistor changed 10 or 15 KOhm p44 Mosfet LM305 IC

Case 3

• Burnt SMD Resistor, Relay and Swollen capacitors.

Luminous Rhino Charge+ 1165

1. Problem – Overloading error and Blown mosfet
   Fault – Mosfet Blown + Faulty gate resistance
   Solution – Found blown mosfet > Mosfet changed > Again checked the gate resistance and transistors > found faulty resistors > resistors changed and problem solved. Video.
   Parts required – 15 SMD Ohm resistance + Mosfet
