We will be looking for the best places to give away the first 20 units. We need to get the most out of these marketing units as there is a ton of competition. Some of it is pretty good, but a lot of it misses the mark.
Feel welcome to send one my way. I will be adding solar to a Sol-Ark 15k with a battery. It is a unique use case for the MS Inverter, but would serve as a demonstration for the general concept:
The MS inveter would attach as AC Solar Input to the Sol-Ark. The 10kW rating of the MS inverter is perfect for my situation.
The Energy Storage Solutions (ESS) program in CT pays a fee (incentive payment) based upon how much your battery supports the grid during "Events" set by the Utility (3 hour window on a specific day when they expect peak demand). Battery ability is after PV production.
My batteries can max out the sol-ark 15k inverter output for that 3 hour window. If I add DC PV, then that cuts into inverter capacity available for the incentive payment.
Why not add a 2nd 15k? Because the utility (Eversource, or ES) limits export to 25kW. Two 15k's can exceed the limit. ES doesn't care about software limits (grid export limit), ES is concerned with hard limits.
Adding 10kW of AC PV would be allowed - the rated AC output of the MN15 (I think I can ignore the peak output of 11kw).
Any excess PV (over 10kW) could be used to charge the batteries (offset power being drawn by Sol-Ark to export power). ESS program only sees what the Sol-Ark inverter is doing, not where the battery power comes from.
Why would MS care about this special case? It could demonstrate that the MN15 could serve as UL1741SB compliant AC PV input to another inverter that can modulate AC PV input.
Bonus if MN15 priority of Solar PV can be: Load, Export, Recharge Battery. And, if Export is Frequency Limited, then excess PV is sent to Batteries. Only when batteries are fully charged would PV production be throttled back.
