Pure sine, 1200 watt, 24 volt DC, 120 VAC inverter/charger. This Hard Wired (HW) model is intended to be wired directly to your household breaker panel. This Samlex EVO inverter offers 1200 watts of high quality pure sine AC power, with a built in battery charger for use with a generator at an affordable price. The charging circuit has several charging profiles to choose from, including full 3 stage charging with equalization. The inverter itself also has positive and negative connection points to tie in a solar charge controller to help simplify overall system wiring.

Reliable, auto transfer between grid and inverter, top quality email support from Vancouver CANADA
I have had an EVO-1224F (1200W, 24V, F = standard duplex 120VAC outlet) running for a year on 200AH of 24V LFP batteries (8 cells) charged by six 'DIYsolarForU' 20A 'Sol' charge controllers (excellent quality, Made in USA). My EVO is running right now as I type this at 800-1000W load. It can run at 110% (1320W) for 30 minutes, 120% (1440W) for 10 minutes, 140% (1680W) for 1 minute, and 2400W for 1/10th second -- which allows great starting capability for small refrigerator and freezer compressors. I like the automatic 'bumpless' (line frequency sync'ing) transfer between grid and inverter based on the voltage of the battery, so that when the batteries get low it just switches to grid power -- the loads (3 computers and the house furnace blower mainly) never notice the transfer to inverter or to grid. When the battery starts to charge the next morning it transfers back to inverter. The inverter is efficient at about 93% and has a low ~7W standby load due to the board which monitors (sync's) the grid and inverter waveforms to be prepared for a bumpless transfer at a moment's notice. My EVO typically runs its inverter 16-20 hours per day depending on load. If the battery voltage gets too low the unit will shutdown completely rather than drain the battery (it can use either lead-acid or LFP batteries). I have found it to be reliable and phone/email tech support out of Vancouver, BC Canada has been excellent. The EVO can connect to generators and can charge batteries (although I don't use it for either). Because the EVO is so versatile it *IS* a little complicated, but the manuals are exhaustive and good quality, and tech support is great. The only very minor downside is the cooling fan, which increases in 4-5 steps from 'unnoticeable' under 600W to 'jet engine' at 1200W. But the necessity of effective cooling is understandable, and I'd rather have it a little noisy than running hot. BTW, you MUST have one EVO-RC-Plus remote control display in order to configure one or more EVOs. There are several EVO models for different battery voltages and power output levels.
