What is the difference between a low frequency and a high frequency inverter?

A low frequency inverter uses a heavy line-frequency (toroidal) transformer, giving strong surge capacity for inductive loads such as air conditioners, pumps, compressors and power tools, which makes it ideal for RVs, trucks, ambulances and off-grid homes. A high frequency inverter uses fast switching with a compact transformer, so it is lighter, smaller and more efficient for electronics and steady loads.

Which inverter can run an RV or travel trailer air conditioner?

A low frequency pure sine wave inverter charger with a built-in transfer switch is recommended. Customers use our 12V 3000W low frequency inverter charger to run travel trailer air conditioning units, with adjustable charger current and charge profiles.

Do you offer OEM and ODM customization for inverters and chargers?

Yes. We customize DC input voltage, charging current, input and output ports, communication protocols, housing and color, input pins, output sockets and LCD displays. Non-standard projects such as a 96V 6000W low frequency inverter for an RV have been engineered for distributors.

What certifications do Maili Electric products have?

Our factory operates an ISO 9001:2015 certified quality management system, and products carry international certificates including CE, RoHS, IP30 and SGS test reports.

Are your battery chargers and isolators compatible with lithium batteries?

Yes. Our 3-stage intelligent battery chargers and intelligent dual battery isolators support both lithium and lead-acid batteries, making them suitable for cars, caravans, marine, EMS vehicles and fire trucks.
