Inverter, not converter. You will need one with or without solar, so no need to wait. I would suggest a PSW unit with a high battery voltage cutoff of 15vdc or higher as depending on battery type and solar controller the charge voltage can approach 15vdc, causing some inverters to go cutoff. This cutoff voltage will be noted in the inverter specs or a knowledgable reseller can guide you to appropriate units.
