To restore a Solark to defaults you will need to input a password (9999).

1 hour is the minimum value the Maximum Absorption Time can be set too. The only way to get around this is to use Assistants to force the Multi to Float after Bulk is finished for X number of seconds. Programmable Relay:  a relay to close based...

Sol-Ark 15Kw inverter/chargers have surge protection on the PV side integrated but not on the AC side. 

There is a problem with the Cerbo with SN- HQ2201xxxxx up and including HQ2220xxxx. Please see document attached to prevent this from happening with future units. Notes from Victron: On the recent batches of the Cerbo GX, there is an error in...

VFXR Inverters are not ac couple capable, per Outback Power.

ALL 15k SolArks must sold with 2 positive and 2 neg cables or single 4/0 set with a jumper on the positive.(Not recommended) Most guys will say it works without but if they use a generator it will throw a false ark fault and it will only charge...

Affected Models: MultiPlus-II, EasySolar-II, Quattro-II  When AC Input was applied, the inverter started charging, but showed zero input amps, therefore, it did not amp limit either. At the same time the inverter would show negative numbers in...

SmartSolar MPPT 250/100 VE.Can – PV input protection change per HQ2150 A change per serial number HQ2150 results in a significantly increased chance of the Smart Solar MPPT 250/100 failing. It then fails with a dead short on the PV terminals,...

You can use 120VAC input on only one inverter (of a split phase system) to charge the batteries if the following steps are taken: The 1ph 120V must go into the L1 unit for this to work. If it is already set up for split-phase, use the VE.Bus...

3 Phase systems can accept 1ph 120V on master L1 unit for passthrough and charging, and the other units will create the other two legs with their inverters. All three inverter create the 3ph with no AC input. You can use it as a 1ph to 3ph...

The fan in the earlier MultiPlus-II, EasySolar-II and Quattro-II units can be noisy, especially at low fan speeds. The electronics design in the recent MP-II/ES-II/QUA-II units has been improved, fixing this problem. Installing the Fan PWM...
