Livguard LGS1700 vs V-Guard Jaadoo 1650
Two 24 V home inverters of about the same size, side by side on the specs each maker states. They differ on output wave, warranty.
- Specs from makers’ pages
- Backup worked out the same way for both
Side by side
“Not stated” means the maker’s page doesn’t give it, not that the inverter lacks it.
