Use Cases

Support connection, replacement, and upkeep

Available accessories address combined inverter-generator power needs, replacement battery needs, selected-load lockout in transfer-switch setups, and routine service for compatible standby generators.

How to Choose

Match the accessory to the equipment

For batteries, compare voltage, amp-hour capacity, terminal configuration where listed, dimensions where listed, and stated generator fit. For other accessories, verify the compatible generator or transfer-switch application.

Applications

Plan around the generator setup

Parallel boxes are intended for two compatible inverter generators. Replacement batteries support compatible generator and solar-generator units, while the contact kit is for a transfer-switch setup managing one selected electrical load.

Additional Information

Review included and reusable parts

The parallel box includes power leads and grounding wires. Many replacement batteries are designed to use the unit's existing cabling and mounting hardware. The maintenance kit includes filters, cleaners, and spark plugs.

Planning Guide

Plan the right fit before choosing

Replacement batteries

Verify electrical ratings and physical fit before selecting

Replacement battery options in this category include 12V batteries with 22Ah, 33Ah, and 100Ah capacities. Many are AGM designs described as maintenance-free, without acid or water to add. Several options are intended for installation with existing cabling and hardware when the replacement match is verified.

  • Match the stated 12V rating and required amp-hour capacity.
  • Check stated compatibility with the generator or solar-generator application.
  • Compare dimensions or footprint where they are provided.
  • Match NB terminals when that terminal configuration is specified.
Power connection and load management

Choose controls based on the job the generator system must perform

A digital parallel box helps connect two compatible inverter generators rated up to 3,300 running watts for combined power needs. It has two IP44 outlets, a 30A breaker switch, and an LED display for wattage, power level, and run-time information at a 50% load. For transfer-switch applications, an auxiliary contact kit helps keep one large electrical load from operating on generator power by interrupting its control-wire signal.

  • Confirm inverter-generator compatibility before using a parallel box.
  • Consider available outlet connections and the dedicated breaker switch.
  • For load lockout, identify the one selected load to be managed in the transfer-switch setup.
Routine maintenance

Use the maintenance kit for the stated standby-generator application

The scheduled maintenance kit groups routine service accessories for compatible air-cooled 11 kW standby generators made in 2013 or later. It includes filters, cleaners, and spark plugs to support routine generator upkeep and engine performance.

  • Confirm the generator is a compatible air-cooled 11 kW standby unit.
  • Verify the generator is from 2013 or later.
  • Review the included filters, cleaners, and spark plugs as part of maintenance planning.
