Hi, how many watts is the inverter?

Your price is quite good and I assume it has a lithium battery charging profile.

I believe that while this unit was marketed under the Microgreen label it was manufactured by Sigineer as a Powerstar LW3000-12 which didn't include a dedicated lithium battery setting. The best Powerstar setting for lithium batteries is AGM-1which provides 14.1V charging and 13.4V float.

I was thinking of Etrek's as having mostly lithium batteries. But there were some lead-acid versions which must be the sellers model. Just trying to get confirmation for prospectve buyers.

I believe the first Etreks only delivered with 8 AGMs with an inverter-charger by AIMS. This was followed by the AGM or lithium option that employed the Powerstar (aka Microgreen) inverter with 8 charging protocols that didn't include a lithium selection. However, prior to RT's demise I think Etreks delivered with batteries and inverter-chargers from KS2 which included an additional protocol for lithiums.

The AGM-1 setting on the OP's offering isn't theoretically ideal but practically it is quite acceptable. We've been using the AGM-1 setting on our ETREK lithiums for over 5 years with no issues.
